ProCodeCG – Private Training – Data Acquisition with ESPectro – Day #1 – 15 May 2017

Standard

Today we had a training on gathering data from sensors using DHT11 and MLX90614 using ESPectro development board πŸ™‚

Setting up before the class started

IMG_8921 IMG_8922

IMG_8923

We used two different computers to make sure we can do lots of things simultaneously πŸ™‚

IMG_8924

we also have to make sure we have reliable internet connection and a toolbox full of anything we might need πŸ˜‰

IMG_8925

we tested MLX90614 with Arduino

IMG_8927

IMG_8929

and it worked. Next we will use ESPectro to be able to send the data via cloud πŸ™‚

IMG_8928

We’re going to use the sensors to measure battery temperature

IMG_8930

We’re going to use multiple sensors to measure multiple batteries, so we’ve got lots of things to do, and will continue the training on Wednesday πŸ™‚

ProCodeCG Kids Regular Coding Class – Arduino Programming – 18 March 2017

Standard

Yesterday Muhammad and his little brother Hasan (those two sitting on the back) helped us to set up the class πŸ™‚ Thanks so much πŸ™‚

IMG_4871

We learned to display sensor readings to LCD πŸ™‚Β We started with LDR (Light Dependent Resistor)

IMG_4877

Raul was a bit confused about the schematic because the LCD and the sensor were in different picture

IMG_4872

but he finally figured it out πŸ™‚

IMG_4879 1

Raul finished the display of ultrasonic sensor reading too, but didn’t have time to continue on temperature and humidity sensor because he had to start his Java Programming lesson πŸ™‚

IMG_4887 1

Koosha’s comfort corner πŸ™‚ (he didn’t want to be in a pic, he left each time we took picture :D)

IMG_4875

Koosha finished the LDR and was tinkering with it but not yet finished the other sensors because there was problem with the library. It’s ok we’ll fix it next week πŸ˜‰

IMG_4881

Ren πŸ™‚

IMG_4878 1

and his serious look πŸ™‚

IMG_4882

Ren finished LDR reading to LCDΒ and ultrasonic reading to LCD. Only on left to try: temperature and humidity sensor πŸ™‚

IMG_4900

Nafis had to catch up with the class

IMG_4880

and he got help from Dad πŸ˜€

IMG_4895 1

and finally got it work πŸ˜‰

IMG_4911

LDR NAFIS πŸ˜‰

IMG_4912

Muhammad had to catch up with the class too so he started with making sure that the LCD works

IMG_4873

And then connect it to LDR πŸ™‚ Next week he’ll catch up with ultrasonic sensor and temperature & humidity sensor πŸ™‚

IMG_4886 1

Ozan had successfully finished the task too πŸ™‚

IMG_4874

We had to change the LDR several times until we found the one with correct readings πŸ™‚ And it finally showing the correct values πŸ™‚

IMG_4885 1

Rafi and Mom πŸ™‚

IMG_4883 1

Great teamwork like always πŸ™‚

IMG_4893 1

LDR reading

IMG_4894 1

and temperature and humidity reading

IMG_4915

In ProCodeCG, a class is not just a regular class. It’s about teamwork and family bonding too πŸ˜‰

IMG_4902

Next week we will explore more sensors and getting started with Espectro πŸ˜‰

 

 

 

ProCodeCG Kids Regular Coding Class – Arduino Programming – 11 Feb 2017

Standard

Today we added the level of difficulty πŸ˜€ We created a schematic for displaying two digit numbers from 0 – 99 using 2 seven segments and 2 shift registers πŸ˜‰

Setting up the class πŸ™‚

IMG_2451

All set up! Raul (on the right arrived very early ;))

IMG_2453

Before class started Clarence showed his wifi detecting with espectro project. He had successfully display it to LCD πŸ™‚

IMG_2456

The LCD displays the wifi ID the device is connected to and the signal strength, plus the number and Β average strength of other wifis detected in range πŸ™‚

IMG_2468

A closer look

IMG_2469

At the end of the class Clarence showed that had successfully display sensor readings from LDR in numbers and progress bar πŸ™‚ Good work Clarence! πŸ˜‰

IMG_2495

Hello Areli! Welcome back little buddy πŸ˜‰

IMG_2457

IMG_2463

Areli had to catch up with the class after missed it for several weeks and he finished the schematic for one digit πŸ™‚ Good work! We will create the 2 digits next week okay? πŸ˜‰

IMG_2477

Ren! Never fails πŸ˜‰

IMG_2458

Ren’s worked just fine πŸ™‚ Keep the wiring because we’re going to add some sensors next week πŸ™‚

IMG_2473

Hello Farrell!

IMG_2459

Ok Farrell was in the mood today! Great πŸ™‚

IMG_2482

He put almost all of sensors he got on his breadboard LOL but the schematic worked πŸ™‚

IMG_2483

A closer look of how messy the breadboard looked πŸ˜€

IMG_2484

Farrell tried to add one seven segment and one shift register but after seeing those cables doubling up the mess he decided to continue that at home or next week πŸ˜€

IMG_2488

Raul! He hated that he had to do what we did last week but when he knew that this one would be able to display 2 digits instead of 1, he agreed to proceed πŸ˜€

IMG_2460

The wires! πŸ˜€

IMG_2461

Raul’s worked straight away πŸ™‚ The first in the class πŸ™‚

IMG_2465

Hello Cinta πŸ™‚

IMG_2464

Cinta did the catching up eagerly today πŸ™‚
IMG_2474

IMG_2471

Yay it worked! Next week we’ll do the 2 digits! πŸ˜‰

IMG_2475

Capt. Malik was a bit frustrated after weeks having problems with his gyroscope library. Apparently because he had compiled lots of projects, there are two Arduino libraries folder in the system that keeps conflicting. We should clean it up and re-install Arduino. Hope it will work, otherwise our Air Drum project will be pending again 😦

IMG_2480

The class πŸ™‚

IMG_2470

We will do more complex but more fun project next week πŸ˜‰

ProCodeCG Kids Coding Camp – Arduino Programming Day #3 – 7 Jan 2017

Standard

Arduino Programming Coding Camp Day #3 πŸ™‚

IMG_0412

We started doing projects πŸ™‚ Kiran started pedestrian crossing project while Salman catching up with the temperature and humidity sensor from yesterday’s task πŸ™‚

IMG_0414

Well Saturday is Saturday πŸ™‚ This is our Saturday be like after 12-days of coding camp in a row πŸ˜€

IMG_0416 1

This one is preparing for national exam while reading some thick books during coding camp πŸ™‚

IMG_0421 1

These two kids are amazing. The have created more than 10 schematic in 3 days πŸ™‚

IMG_0420 1

Kiran rarely makes mistakes πŸ™‚

IMG_0422

Salman is very persistence typing the code, even though he can’t type as fast as he creates the schematic πŸ™‚

IMG_0423

The temperature and humidity sensor works πŸ™‚

IMG_0424

Temperature: 22 Celcius and Humidity: 62

IMG_0425

This Captain wanted to do pedestrian crossing project too

IMG_0426

Salman started to moved to pedestrian crossing project

IMG_0427

Kiran’s has worked just fine. Well done πŸ™‚

IMG_0433

And Salman’s too πŸ™‚ The picture show the state when the pedestrian is not allowed to cross because the red light on the left is on while the “green” light on the right is on. So in this state, cars will cross the road and pedestrian should press the button to set the pedestrian light to green and cars light to red πŸ™‚

IMG_0438

After we finished the first project, the next is to measure height using ultrasonic πŸ™‚

IMG_0441

Capt. Awa helped Salman to debug the code πŸ™‚

IMG_0442

Okay the schematic is ready we’re measuring heights πŸ™‚ Salman is 125cm

IMG_0443

IMG_0444

Capt. Fizhan is 150cm. Kiran is 140cm (no picture)

IMG_0445

Next project: Battery tester πŸ™‚

IMG_0447

Awa still working on Salman’s height measuring coding

IMG_0448

Battery tester schematic is quite complex πŸ™‚

IMG_0449

Capt. Awa gave up and Capt. Zaki came to fix Salman’s height measuring coding (later we found out that the code didn’t print the sensor reading LOL)

IMG_0451

Yaaay after lunch Salman finally finished his battery tester project πŸ™‚ This shows that the battery is half/medium capacity because the LED in the middle is on

IMG_0454

This one shows a battery with low capacity because the red LED is on πŸ™‚

IMG_0456

Kiran’s battery tester works too πŸ™‚ It shows the same result as Salman’s for the same batteries πŸ™‚ This one is low capacity

IMG_0457

And this one half capacity

IMG_0458

We did try to add some buzzer to the schematic but still didn’t work. We’ll figure out later πŸ™‚

IMG_0459

Yaaay, these two has just finished Arduino Programming Coding Camp! They’re now as good as kids in Arduino Programming Regular Class πŸ™‚

IMG_0462

See you on the next Coding Camp in the next 6 months πŸ™‚

ProCodeCG Kids Coding Camp – Arduino Programming Day #2 – 6 Jan 2017

Standard

Arduino Programming Day #2 πŸ™‚ We learned about sensors πŸ™‚

IMG_0305

The first sensor is LDR (Light Dependent Resistor)

IMG_0306

Capt. Fizhan makes his own schematic too

IMG_0308 IMG_0309

Done and works well πŸ™‚

IMG_0310

“Don’t take my pic” gesture of every captain is a common thing in our classes πŸ˜€

IMG_0311

Salman might look so small but he can follow the lesson πŸ™‚ The only obstacle is that he has to deal with lots of typing (which is not his fault πŸ˜€ )

IMG_0312

Kiran is very quiet but persistence πŸ™‚ She constantly finished the task one by one with very few errors. This girl has got a brain wiring that works like electronics πŸ™‚

IMG_0313

Capt. Syahna before unloading her laptop and thick book πŸ˜€

IMG_0314

Salman’s Dad is being productive too πŸ™‚ He moved his office to this corner with kids carpet and little smiley table πŸ™‚

IMG_0315

Capt. BR moves his office too πŸ˜€

IMG_0324

Capt. Awa and mom also moved their office to the class πŸ™‚ Yeaay the more the merrier πŸ™‚

IMG_0347

IMG_0316

Next we add LED to the LDR schematic so that when LDR receives low light, the LED will light up πŸ™‚

IMG_0317

The schematic is a little bit tricky

IMG_0319

It took some time to make it work

IMG_0320

IMG_0325

Still not working

IMG_0326

Need some debuggin

IMG_0333

almost giving up

IMG_0334

He changed the LED and Capt. Zaki came for some help

IMG_0329

and it finally worked πŸ™‚

IMG_0335

Salman is still working on his

IMG_0321

and so is Kiran

IMG_0322

There was some errors

IMG_0323

Capt. Zaki come to debug

IMG_0327 2

and also Capt. BR

IMG_0330

Took some time to figure it out

IMG_0331

And it finally worked πŸ™‚

IMG_0332

Salman’s worked too πŸ™‚

IMG_0338

Next is buzzer πŸ™‚

IMG_0336

This one is quite easy πŸ™‚

IMG_0337

Capt. Fizhan helped Salman with the schematic because the buzzer wouldn’t work

IMG_0339

IMG_0340

After we got that one worked, we continued to ultrasonic sensor πŸ™‚

IMG_0341

IMG_0342 IMG_0343

Capt. Awa helped Kiran to find the correct source of code for ultrasonic sensor

IMG_0344

while Capt. Zaki working on Salman’s

IMG_0345

πŸ˜€

IMG_0346

IMG_0348

This is how Capt. Awa looks like when he cannot decide where to put a new sticker: on his laptop or on his toolbox πŸ˜€

IMG_0349

Salman’s ultrasonic didn’t work because some wirings are still not correct

IMG_0351

after some re-wiring, it worked πŸ™‚

IMG_0352

Captain Corners πŸ˜€

IMG_0353

Capt. Awa assisting Salman. They’re in the same age πŸ™‚ So cute πŸ™‚

IMG_0354

Capt. Awa testing Kirana’s potentiometer with LED

IMG_0355

Salman is still tinkering with his ultrasonic with buzzer

IMG_0356 IMG_0357

IMG_0358

After checking on everybody Capt. Awa decided to do some experiment with a relay πŸ™‚

IMG_0359

The last task for today is temperature and humidity sensor

IMG_0360

Kiran has made it work

IMG_0361

Salman will catch up on that one tomorrow πŸ™‚

IMG_0362 2

We have gone through all of this today! Yaay

IMG_0350

This is a picture of Capt. Awa cleaning up the room LOL He ran away πŸ˜€

ProCodeCG Kids Regular Coding Class – Arduino, ESPectro, Apps Programming – 15 Oct 2016

Standard

Our ProCodeCG Kids Regular Coding Class yesterday πŸ™‚ We’ve been splitting the class into two: 9 – 10:30 for Arduino/ESPectro Programming and 10:30 – 12 for Intro to Programming, GameMaker, Java Programming and Apps Programming.

But yesterday there were only 2 kids coming for the second class so we will compile the report into one report here πŸ™‚

The class in the morning, Awa and some students arrived earlier and it is almost sure that Awa set up the class again like last week πŸ™‚

IMG_4423

Today we’re going to explore temperature and humidity sensor πŸ™‚

IMG_4424

Ozan was getting ready with the board and looking at the screen for the scheme
IMG_4425

Clarence was busy tinkering with his ESPectro board

IMG_4426

Muhammad was going to test LDR sensor because it didn’t work last week
IMG_4427

Renald busy opening the handout on his smartphone

IMG_4428

Awa decided to play with ultrasonic sensor πŸ˜€ He plannedΒ to test his new LCD module but got distracted with the ultrasonic πŸ˜€
IMG_4429

Ok apparently Renald’s Mom had printed the handout so Ren was good to go! πŸ™‚

IMG_4430

The schematic
IMG_4432

Clarence had problems with USB UART Driver for ESPectro. This happens a lot on Windows Β 7

IMG_4433

Awa is always interested in whatever Clarence is doing πŸ˜€
IMG_4434

We love each other yaaay πŸ™‚ Sweet! πŸ™‚
IMG_4435

Rheino was busy doing his schematic

IMG_4436

IMG_4438

Muhammad, Zahran and Ren
IMG_4437

Darrell forgot to bring his Arduino Kit but he can use the teacher’s so all good πŸ™‚
IMG_4439

IMG_4443

Some were having breakfast πŸ˜€

IMG_4440
IMG_4441

More kids were coming, including the twins! πŸ™‚

IMG_4442

Capt. Malik showed up with LOTS of new things. He was working on his robotic project
IMG_4444

He bought Arduino Mega
IMG_4445

And joystick

IMG_4454

And motor servo etc. πŸ˜€

IMG_4446

One of the twins Michael and Kevin (we still cannot tell the difference πŸ˜€ )
IMG_4447

Yaay Darrel temperature and humidity sensor works πŸ™‚

IMG_4448

Everybody was busy. Including some parents πŸ™‚
IMG_4449

The twins’ dad is very good programmer. He knows this stuff very well πŸ™‚

IMG_4450

Ozan had to use two set of boards to finally found out that the problem was on the sensor driver πŸ˜€
IMG_4452 IMG_4453

Same thing happened with Ren’s computer (later his Mom fixed it by manually copying the DHT library to Arduino/libraries directory)
IMG_4455

Ren’s Mom helped Ozan with the driver
IMG_4456

And it finally worked and Ozan said “OK, I can go home now!” LOL

IMG_4457

Then we got a newcomer in the Intro to Programming class: Robbie πŸ™‚
IMG_4458

Kids from Arduino Class still have lots of things to do so they stay with the next class because we only have two kids in the next class πŸ˜€

IMG_4459

The twins
IMG_4460

and their works

IMG_4461

This is what Darell did yesterday. An app with button showing a minion πŸ˜€ Yaaay!

We have zillions things to do next week, will be reporting again! πŸ™‚

ProCodeCG Kids Regular Coding Class – Arduino Class – 17 Sep 2016

Standard

Hello Indonesia, every Saturday Indonesian kids learn about IT and programming so they will be able to cope with the challenges in the future and make Indonesia proud πŸ˜‰

IMG_2518

In our Arduino Class yesterday we continue our Arduino lessons and learning some functions πŸ™‚

IMG_2519

Muhammad (in front) and Reza (behind) were setting up their kit to continue their work. In the corner is the helpful Mom of Renald πŸ™‚
IMG_2521

Aliyah is the only girl in the class πŸ˜‰ She is always very quiet but she always get things done πŸ™‚ She never complains typing lots of lines of codes πŸ˜‰

IMG_2522

Azriel, was busy with his LED, resistors and jumper wires. He said he made almost all of his resistors curly so apparently we have to shop for more resistors LOL πŸ˜€
IMG_2523

Areli complained about having to create the same layout on his breadboard again but he finally did it πŸ˜€ the wiring was the same but we were learning different code πŸ˜‰

IMG_2524

Hello Darrell! You have to type some code on the screen πŸ™‚ Lots of line but believe us it’s gonna worth it πŸ˜‰
IMG_2525

Rezandra was on his new project: making his sound sensor work πŸ˜‰

IMG_2527

He just wouldn’t stop until it worked! πŸ˜€

IMG_2537

Newcomers! Ozan and Tristan started to unbox their ProCodeCG Arduino Kits and learn with us πŸ˜‰
IMG_2528

Tristan had just registered and start to join both classes yesterday πŸ™‚

IMG_2529

Ozan started a bit ahead yesterday, he had downloaded the software and plugged the Arduino in πŸ™‚
IMG_2530

Clarence! He was working on his chicken coop temperature and humidity control project πŸ™‚ (and yes, he didn’t like us taking his pic :D)

IMG_2531

Zahran examined his board very carefully because it wasn’t working since last week (later we found out that his computer had some problem with the driver)
IMG_2532

Ren had finished ALL the task in handout (we should update it very soon! πŸ˜€ ) Well done Ren! You are so fast! πŸ™‚

IMG_2533

Ren’s alternate blinking LED

IMG_2545

Malik had successfully made ultrasonic sensor work. Yesterday he tried temperature and humidity sensor, but still didn’t work.
IMG_2534

IMG_2538

Reza forgot to bring his Arduino Kits, oh nooooo (he had to wait for his father to deliver it for him)

IMG_2535

While we were waiting for another ProCodeCG Arduino Kits to be shipped via Gojek πŸ˜€ Tristan and Ozan had to share one kit together. Which was good so they could leard to do teamworking πŸ™‚

IMG_2539

Ozan got his LED on breadboard blinked. Then it was Tristan’s turn.

IMG_2540

ProCodeCG class is always full of inspirations and bright minds πŸ˜‰ This is Ren’s Mom helping Aliyah with her computer. Apparently for some Windows versions, there are problems with Arduino driver and compiler (we’re going to release some troubleshooting handout very soon πŸ˜‰ )

IMG_2541

Muhammad had problems too and he worked really hard, solving every error occured

IMG_2542

And finally it worked! (what with that face though? LOL)

IMG_2549

And finally Rezandra had his sound sensor worked!
IMG_2552

With the help of another parent, Pak Slamet, thanks pak! πŸ™‚

IMG_2553

There were some adjustment need to be made like the threshold of sensitivity and so on.
IMG_2554

Wow, it’s not only ProCodeCG Kids that are so cool, the parents too! πŸ˜‰
