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

Our Saturday tinkering 🙂 Today we display temperature sensor reading to two seven segments 🙂

Ozan, like usual, didn’t want to be in a pic 😀

Nafis scratched his head finding out that we’re still continue the crazy and tangled wiring 😀

This is what Nafis was working on 😀

Clarence! Came with LOTS of ideas 🙂 Today he explored his new TFT LCD with ESPectro 🙂

Clarence tried every library and example he found, and modified them to see what happen 🙂

Reza was back yaaay 🙂 He had to do lots of catching up 🙂

Hello Ren 🙂

After struggling with overheated temperature sensors, and the not-showing-the-value seven segments

It finally worked! Yaaay Ren 😉

Raul was terrified knowing that we were using schematic from last week while he had pulled up all the wires and component 😀 But he had enough patience and persistence to do it all over again 😉

Raul’s schematic might still not working properly, but the code was. We connected his code to a ready schematic and it worked correctly 🙂

Aaand, we had a new student today 🙂 His name is Koosha 🙂

He already had a super complete toolbox, and he already understands LOTS of things 🙂 He’s been learning by himself via YouTube but his father said he needs to be guided to the right direction so here he was in ProCodeCG Class 😉

Koosha started with multiple function button and then moved on to ultrasonic and buzzer. Later he add LED to the schematic and tried the ultrasonic piano 🙂

Next week we’ll do different project with different components 🙂 We think kids are fed up already with the seven segments 😀

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

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

Setting up the class 🙂

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

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

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

A closer look

At the end of the class Clarence showed that had successfully display sensor readings from LDR in numbers and progress bar 🙂 Good work Clarence! 😉

Hello Areli! Welcome back little buddy 😉

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

Ren! Never fails 😉

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

Hello Farrell!

Ok Farrell was in the mood today! Great 🙂

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

A closer look of how messy the breadboard looked 😀

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 😀

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 😀

The wires! 😀

Raul’s worked straight away 🙂 The first in the class 🙂

Hello Cinta 🙂

Cinta did the catching up eagerly today 🙂

Yay it worked! Next week we’ll do the 2 digits! 😉

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 😦

The class 🙂

We will do more complex but more fun project next week 😉

ProCodeCG Kids Regular Coding Class – Arduino Programming – 4 Feb 2017

Hello! Today we arrived early enough to witness and capture Capt. Awa setting up the classroom 🙂

Capt. Awa has a very tight standard about the arrangement so we made sure we follow the order and setup had been laid out 😀 Look how the mat and the tables were neatly placed 🙂

Raul came early and started to work right away!

We created a schematic of shift register and seven segment today 🙂

Raul complained about the number of resistors involved. He said “They are only slowing me down!” 😀

Raul’s didn’t work, we checked the wiring and got dizzy, and we found out later that the seven segment wasn’t placed correctly LOL 😀 Let’s fix it next week Raul 😀

Abit arrived early too. He continued the lesson from handout: button 🙂

Abit learned button to turn on and turn off LED onboard, LED on breadboard, and multiple function button.

Capt. Awa doesn’t really like seven segments 😀 He hates the wiring *this is how he looked like seeing the schematic on the display 😀

Even with the presence of his senior, Capt. Awa was still frowning 😀

A great teamwork 🙂

Capt. Awa’s wiring 😀 It is clear why he dislike seven segments 😀

Meanwhile, Nayla, little sister of Nafis was diligently putting her brother’s Arduino stuff into a new toolbox 🙂

Nafis was glad to have a new toolbox but seemed to hate seven segment wiring just like Awa 😀 Hang on kids, once you get used to it, we can create great things 🙂

Rafi undergone the same path as Abit today: learning about button 🙂

Rafi forgot to bring his toolbox, so he used ProCodeCG’s 🙂

Clarence wanted to do the class project today (he probably not in the mood working on his wifi project :D)

He wanted to learn about shift register

Clarence’s didn’t work probably because he used common cathode instead of common anode (which we refer in the class today), or probably there were some incorrect wirings, or he used different set of array for the seven segment. We will find out 🙂

Ren was the only one sticking with common cathode seven segment. So he had different wirings and code 🙂

And Ren’s worked 🙂 As usual 😉

Rheino didn’t bring his toolbox because he left it in Jakarta. So he borrowed Awa’s Arduino board and ProCodeCG’s breadboard and stuff 😀 That’s why we have two group of wirings to double up the headache here LOL

Rhei’s wiring seemed to be correct but it didn’t work. We will debug it or start from scratch again next week 🙂

Ozan was in a great confuse looking at the schematic, just like everybody else in the class 😀

So we did it together and phew! Ozan’s worked well, yaaay 🙂

Dika started his first Arduino lesson today 🙂

He learned to turn on LED onboard, LED on breadboard and RGB LED 🙂

He also learned to turn on multiple LEDs alternately

RGB LED worked just fine too 🙂 Dika took 2 classes today on the same topics: Arduino, because he couldn’t stop 😀

The class today 🙂

Next week we will add up the difficulty: we will use 2 shift register and 2 seven segments 🙂

 

ProCodeCG Kids Reguler Coding Class – Arduino Programming – 21 Jan 2017

Our Saturday fun 🙂

We had lots of kids today with loads of idea and projects to do 🙂 Farrell brought his idea to create SSTV to transmit image via radio with Arduino 🙂

Capt. BR should lecture Farrell about information theory 🙂

While Ren, as usual, try the latest lesson and test whether it works or not 😀 It is schematic to light up LEDs alternately using two buttons and a shift register 🙂

Abit had just joined our reguler class (he joined our coding camp last month :)). Abit is a fast learner 🙂

Hello Areli! It’s really nice to have you back! Please be patient with this complicated schematic and long codes 🙂

Capt. Malik was given a task to explore gyro for creating air drum prototype 🙂

The view of: Vallo having headache and Ren seriously typing the code from the manual on his android phone 🙂

Raul (black shirt) was upset about his not working seven segment with two buttons last week. Today he created the schematic of seven segment that shows numbers entered from Arduino serial monitor

And it worked yaaay 🙂 Raul is so happy 🙂

Abit and his multiple LED 🙂 He looks bored with that hand under the chin but he’s actually very excited 🙂

Farrell and his SSTV,  reading radio signal and convert it into data

Ren’s schematic works just fine 🙂

Well done Ren, thanks! 🙂

Ozan’s seven segment with serial input monitor works too 🙂

Rafi started from the very beginning about Arduino today, to make sure he understands the required theory to get started 🙂

Clarence came up with his wifi and Espectro project 🙂

Areli and his schematic. Kids tend to dislike seven segments wiring because it looks complicated with all the wirings 🙂

The class

Capt. BR teaches Vallo about components and how they actually work

And Vallo starts the seven segment with two buttons schematic

Rafi looks so excited about his multiple LEDs 🙂

Capt. BR shows Vallo how to use ProCodeCG Button 🙂

Heeey, Capt. Reza glad to have you back! Reza is a very focus and persistent kid. He wouldn’t stop until he makes it work 🙂

This is Farrell and Clarence in a deep discussion about SSTV etc 😀

The should do this project together 😀

The signal encoding 🙂

Phew, lots of things going on in this class today, and the success rate is higher than last week 🙂 Hoping to create more interesting things next week 🙂

ProCodeCG Kids Regular Coding Class – 14 Jan 2017 – Arduino Programming

Hello Saturday 🙂 Our regular class is back 🙂

Ozan and Rafi. Rafi looks so stressed, why? 😀

Those two: Capt. Awa and Fizhan 🙂

Ren, always one step ahead 🙂

Capt. Cinta and Capt. Syahna 🙂

Raul!

We had two projects today: one is potentiometer to control brightness of LED and seven segment with two buttons: one for counting up and one for counting down 🙂

Looks empty but more kids were coming in later 🙂

Nafis is back 🙂

That face 😀

Ozan had finished the schematic and ready to type in the code

Rafi was still installing Arduino software 🙂

Ren had finished the seven segment count-up count-down 🙂

Capt. Malik was also in the class, very quiet as usual but working a lot 😉

Ren showed the code to set the seven segment through Arduino serial monitor 🙂

Rezandra’s potentiometer schematic

Raul had finished the first one and got very frustrated about the second 😀

Rafi’s worked too 🙂

Awa’s 🙂 He hadn’t added the two button yet 🙂 Let’s try it next week 😉

Capt. Malik also hadn’t figured out the second project. So we probably should try it again next week 🙂

So glad to have these kids again every Saturday 🙂 We’re going to have more fun next week 😉

ProCodeCG Kids Regular Coding Class – Arduino Programing – 7 Jan 2017

We’re back 🙂 Only these three coming actually 🙂 Probably because we announced that we open regular class only this morning 😀

We had Vallo, Capt. Awa and Zahran 🙂

Capt. Awa was given assignment to assist Vallo with potentiometer and seven segment 🙂

Look at these two 😀

Awa was working on his joystick and infrared sensor while assisting Vallo 🙂

Zahran started to open his toolbox after almost a month 😀

Zahran LED with potentiometer didn’t work so Capt. Zaki gave him a help

Yaaay, Vallo’s potentiometer and LED works 🙂

He is smiling behind that mask 🙂

Vallo showed his schematic to his father 🙂

Some boys chit chat 🙂 (Vallo’s dad is very friendly :))

While Capt. Zaki and Zahran was still figuring out what’s wrong

And, it finally worked after we found out that the ground went across the middle of the breadboard. We just put a jumper to connect the middle line and it worked just fine 😀

The next is seven segment 🙂

Zahran’s seven segment didn’t work

While Capt. Awa was visited by the Senior

And he showed how a relay works 🙂

Finally, after Vallo’s seven segment worked and he got home, Zahran’s worked too. They’re given to make the seven segment counting down 😉

See you next week 🙂

ProCodeCG Kids Regular Coding Class – Arduino Programming – 24 Dec 2016

Yesterday we learned a new component: seven segment 🙂 This class started at 1 pm because there was another schedule in the morning. Not so many kids could make it to the class, but we had enough to start the class 🙂

Nafis was back after several weeks 🙂 Welcome back Nafis 🙂

Farrell was ready to explore his new TFT display and connect it to a gyroscope 🙂 He needs to figure out how to make it work before displaying the data readings from gyroscope.

Nafis’ mom is an electrical engineer, so he really had a great help there 🙂

Capt. Fizhan helped Nafis to get started 🙂

We use common anode seven segment to display numbers from 0 to 9. Renald used common cathode one and it worked as well 🙂

Rezandra missed several classes, and it was great to see him in class again yesterday 🙂

Ren finished his really quick and started to explore how to input the number from serial monitor 🙂

And our Lead Captain was back too, Capt. Zaki 🙂 He was really busy during his first year in high school, now he is catching up with the class to be able to assist the upcoming kids coding camp 🙂 Farrell asked lots of technical things to Zaki 🙂

Captain Malik! 🙂

Capt. Malik with his new ProCodeCG Jacket 🙂

Capt. Zaki catching up with Arduino stuff

Rheino examined his schematic very carefully 🙂

Raul (wearing grey shirt) is new to the class (this one is his second) but he could read the schematic very well 🙂

Ren’s working nicely

While Capt. Malik preferred to tinker with his new 8×8 dot matrix LED 😀

Ok it worked and there’s so much thing we can do with this thing 🙂

Malik drew this cute creature

Or smiley

The next challenge for Malik is to make this object shift from left or right 🙂

And the next challenge for the class is to enter a number from 0 – 9 from the serial monitor to be displayed on seven segment 🙂

 

ProCodeCG Kids Regular Coding Class – Arduino Programming – 12 Nov 2016

ProCodeCG Kids Arduino Class yesterday 🙂

Setting up the class in the morning 🙂

Even parents help 🙂

Nanin (little girl on the left) arrived early for her 10:30 class but it’s ok because Capt. Cinta (middle) and Capt. Syahna (right) were ready to help her continuing the lesson 😉

Only a few kids in the morning because lots were coming late 🙂

Clarence had several things to do so he started gearing up

Areli was ready to catch up with the class he missed 🙂

Zahran and Ren, always excited to try new things 🙂

Ozan was ready to catch up too

Ren showed parking warning system he did at home. When the distance is less than 5cm the red light will be turned on and when there is no movement for 5 secs the green light will be turn on.

Kids gobble up everything we teach and turn it into amazing things.

Areli was so patiently typing the code because he really wanted to see the schematic works 🙂

The nicest thing about our class is always: friendships 🙂

Rezandra came late but he always catches up 🙂

 

There he is our Captain Malik 🙂 He always got lots of things on mind, waiting to be challenged 🙂

Yesterday we learned about how to make a button serves multiple functions 🙂 Pressing the button in short time will light up one LED and pressing it longer will activate the other LED.

Clarence was doing different thing. He’s on a mission to make a seven segment work.

And he did 🙂

The seven segment do counting from 0 to 9. Next assignment is to use two seven segments and make them count from 00 to 99.

The first one who finished the circuit and made it work is Ozan 🙂 Then he helped others to make theirs work 🙂

To those who have finished the multiple function button can try to make a buzzer activated by an ultrasonic sensor.

Ren’s multiple function button didn’t work and his mom had to help 🙂

Apparently the Arduino Sofware version needed to be updated, then the problem was solved 🙂

We told Capt. Malik about our next project including the flood warning system prototype, and he was just open his magic toolbox and started to work 🙂

He was testing the buzzer and will activate it using an ultrasonic sensor

Rezvan is always interested in whatever his brother doing. He is going to be as good as Malik 🙂 (in the background: Ren’s mom helping Zahran to fix his :))

Capt. Malik’s gears.

We’ll see what the kids will come up with next week 😉
