Rezky is working on ultrasonic counter πŸ™‚

IMG_4085

IMG_4106

Awa continued exploring ESPectro

IMG_4086

There were some problems occurred

IMG_4101

Undetected serial port and the absence of 2 pins connector πŸ˜€ At the end the code and neopixel worked just fine with another ESPectro 2 pins connector πŸ™‚ So we just need to get that tiny connector and next week Awa can move on the next level πŸ˜‰

IMG_4109

Ren was back πŸ™‚ Working on ultrasonic counter πŸ™‚

IMG_4088

Having problems uploading the code to the board

IMG_4103

But worked using different computer πŸ™‚

IMG_4132

Yes, programmers often have times like this, when everything went wrong don’t know why πŸ˜€

IMG_4133

The most successful one is Ozan πŸ™‚

IMG_4100

He had successfully created a charging battery animation, with no fuss πŸ™‚

IMG_4115 IMG_4116

IMG_4117 IMG_4118

IMG_4119 IMG_4120

Next week things will work just fine and we will create more projects πŸ˜‰

ProCodeCG Kids Regular Coding Class – ESPectro Programming today πŸ™‚

IMG_3259

We had a newcomer, Emma πŸ™‚

IMG_3260

Emma is interested to learn C so she was given an intro to Arduino to try some C-like language πŸ™‚

Hello Rafi welcome back πŸ™‚

IMG_3261

Rafi picked up where he left more than a month ago πŸ™‚

IMG_3281

He created an animation of charging battery πŸ™‚

IMG_3285

IMG_3286

IMG_3287

Raul was also catching up with stuff too πŸ™‚ He was working on synchronized clock via internet through wifi on board ESPectro πŸ™‚

IMG_3262

Ruben had finished multiple LEDs last week. Today he learned about RGB LED

IMG_3273

IMG_3274

IMG_3290

Under Capt. Faris’ supervision πŸ˜‰

IMG_3263 IMG_3264

IMG_3277

This cute little guy took notes! A rare scene! Kids should be taught to do this! πŸ™‚

IMG_3282

Ruben seems to have another calling too: drawing πŸ™‚

IMG_3283

IMG_3288

Ok, with Capt. Faris assistance,

IMG_3291

Ruben has also finished to make a button worked too πŸ˜‰

IMG_3309

Hello Rezky πŸ™‚

IMG_3265

Rezky fixed what didn’t work the last time

IMG_3275

He redid the button and button to serial section, and both worked nicely!

IMG_3279

IMG_3280

IMG_3284

Abdillah was given a task to create a counter with an ultrasonic sensor

IMG_3266

It worked perfectly with an Arduino πŸ™‚

IMG_3267

The ultrasonic sensor will count how many objects detected πŸ™‚

IMG_3268

Next is to make this work with ESPectro so we can send the data via cloud πŸ™‚

IMG_3269

and make LCD I2C works with ESPectro

IMG_3305

Abdillah was helping Rezky with library errors πŸ™‚

IMG_3293

Rezvan was back too πŸ™‚ Β Working with button to serial

IMG_3306

And worked nicely! Next is button with LED πŸ™‚

IMG_3307

Capt. Malik (started to have being in a pic :D) was working on air-drum project πŸ™‚

IMG_3308

We’ve got lots of project going not only in the class but also when the kids are off the class πŸ˜‰ There gonna be lots of progress next Saturday πŸ™‚ Can’t wait πŸ˜‰

 

ProCodeCG Kids Coding Camp – IoT Programming – Day #3 – 24 June 2017

Standard

IoT Programming Coding Camp Day #3 πŸ™‚

Today we connect to a MQTT server to be able to publish and subscribe to a topic so we can control our ESPectro remotely via cloud πŸ™‚

We connected to a MQTT server running on one of the computer of the class and also connected to an online MQTT server πŸ˜‰

IMG_2259 IMG_2260

IMG_2261 IMG_2263

IMG_2265 IMG_2266

IMG_2267 IMG_2268

IMG_2269

We can control the ESPectro via mobile too πŸ™‚

IMG_2273

IMG_2274

The lessons today required hard work and patience πŸ™‚

IMG_2278

ProCodeCG Kids Coding Camp – IoT Programming – Day #1 – 22 June 2017

Standard

Day #1 of IoT Programming πŸ™‚ We have 3 kids for this topic πŸ™‚

Today we did some ESPectro setup and configuration, and then started basics about ESPectro. We learned about LED, button and neopixel. We created some cool stuff about neopixel on board, like creating knight rider and traffic light with pedestrian button πŸ˜‰

IMG_2067

Here’s the pics of each kid with their works πŸ™‚

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 – ESPectro Programming – 29 April 2017

Standard

Hello Saturday πŸ™‚ This class is what makes every Saturday so fun πŸ™‚

IMG_7716

This little girl is Alice, she is Azriel’s sister, and she was the most helpful person today!

IMG_7717

Alice set up the class voluntarily πŸ™‚

IMG_7718

Preparing things like this is a good training for kids, it is amazing that a kid this young is already aware about giving help πŸ™‚

IMG_7719

Go Alice πŸ˜‰

IMG_7720

Ren (on the left) moved aside to give Alice space to work πŸ˜€ πŸ˜€ πŸ˜€

IMG_7721

All set! Thanks so much Alice πŸ™‚ ❀ ❀ ❀

IMG_7722

More kids were on their way πŸ™‚

IMG_7726

Like usual, the first thing to do is downloading the newest version of handout πŸ™‚

IMG_7727

Today we learned how to scan wifi, and this is Ozan’s πŸ™‚

IMG_7745

Reza working on wifi scanning

IMG_7728

Once it worked, Reza moved on to the next task

IMG_7751

… connecting ESPectro to a LCD I2C so next we will be able to display wifi statusΒ to it πŸ™‚

IMG_7785

Ren πŸ™‚

IMG_7729

… and Mom. When these two get together, there’s nothing they can’t do

IMG_7735

because they are a great team πŸ™‚

IMG_7765

Danesh was catching up with button and LED

IMG_7730

He had successfully control LED by pressing the button, and toggle its function too πŸ™‚

IMG_7736

Raul won’t stop until everything works πŸ˜€

IMG_7731

He finished the wifi scanning and and connecting ESPectro to LCD I2C πŸ™‚

IMG_7752

Clarence had lots of achievements today πŸ™‚

IMG_7758

He had successfully display active wifi to a TFT display, complete with the strength of the signal πŸ™‚

IMG_7737 IMG_7738

And Clarence also code an algorithm to sort data and display it πŸ™‚

IMG_7759

The process of sorting πŸ™‚

IMG_7788

IMG_7760

Clarence’s stuff πŸ˜€

IMG_7762

Pak BR gave a task of data visualization with Python to Clarence πŸ˜€

IMG_7784 2

Pak Budi had his own project too

IMG_7744

Including fixing the broken extension cable by creating an emergency voltmeter πŸ˜€

IMG_7742

Also had a discussion with one of the parents (one of those geek parents :D) about IoT πŸ™‚

IMG_7787

We learned so much today

IMG_7740

and got so much guests too πŸ™‚ Bubi, Azriel’s mom was there to share about family and communication πŸ™‚
