ProCodeCG Kids Regular Coding Class – Arduino/ESPectro Programming – 16 Sep 2017

Standard

The class is ready 🙂

IMG_8013

Today we are ready to explore new component: micro servo 🙂 Nafis is ready 🙂 *notice the screwdriver and the breadboard on his forehead LOL

IMG_8019

Nafis is so excited to see how a micro servo work 🙂

IMG_8024

IMG_8025

Nafis hasn’t finished typing the code so we’re going to try it next week 😉

IMG_8034

While Rezky still needs some time to test his new LCD I2C (we replaced the previous one with a new one)

IMG_8014

the new one didn’t work so we give him the working one and going to claim this one with another replacement. So Rezky will start exploration next week 🙂

IMG_8023

Reza is back 🙂

IMG_8015

He has to catch up with several previous projects before he can start his new project 🙂

IMG_8020

Project for Reza today is Ultrasonic Counter 🙂

IMG_8040

He struggles with libraries and the schematic. Still have to work on it next week 🙂

IMG_8071

Cinta learns robotic at school, and apparently what she has learn in ProCodeCG classes turn out to be very useful 🙂

IMG_8016

The code Cinta developed to turn on a set of LEDs to light up in a certain pattern according to what we enter from serial monitor

IMG_8026

IMG_8027

Cinta still has the schematic on the breadboard

IMG_8028

These for LED’s will blink in a pattern defined from serial monitor

IMG_8031

IMG_8033

Awesome work, Cinta 🙂

IMG_8032

Next week we will do more projects and fix bugs and errors 🙂

IMG_8022

Glad to know that our class helps kids with their school 🙂

IMG_8018

We’ll be reporting again next 🙂

ProCodeCG Sensor Data Acquisition Training – 11 Sept 2017

Standard

Today we trained lecturers for Politeknik Negeri Pontianak on how to do data acquisition from current sensors 🙂

Class preparation

IMG_7660 IMG_7661

We split the team into two: hardware and software. The hardware team started to assemble the components

IMG_7662

while the software team installing the application and libraries

IMG_7663

IMG_7664 IMG_7665

IMG_7666

ESPectro basic testing: blink

IMG_7667

and neopixel animation

IMG_7668

Then we’re ready to connect ESPectro to the circuit and sensor

IMG_7670 IMG_7671

IMG_7672

We compared the circuit with the one that has been tested and verified

IMG_7673

IMG_7674

Still didn’t work

IMG_7675

It took lots of retrying, switching components and we tried every solution possible and think of every source of errors

IMG_7676

still didn’t work

IMG_7677

We just kept trying

IMG_7678 IMG_7679

and after we changed the resistors with metal film ones, it worked! 😀

IMG_7680

Current reading when the switch is on

IMG_7681

when off

IMG_7683

when on and off again

IMG_7682

The effort was worth it 🙂 We finally finished the training and ready to collect data for further research and analysis 🙂

ProCodeCG Kids Regular Coding Class – Arduino/ESPectro Programming – 9 Sept 2017

Standard

Our Arduino/ESPectro Programming Class this morning 🙂

IMG_7459

Ozan was ready to modify automatic pedestrian traffic light with ultrasonic 🙂 We were going to add LCD to display information to pedestrian 🙂

IMG_7460

It worked 🙂

IMG_7478

The display will show the color of the traffic light:

red

IMG_7479

yellow

IMG_7481

green. Ozan had to change all the text into some info for pedestrian so they will know when to cross and how many times left 🙂

IMG_7482

Nafis

IMG_7462 2

and Rezky were working on the same project as Ozan

IMG_7463

These two like to work together

IMG_7468

helping each other finding bugs and make the schematics 🙂

IMG_7476

IMG_7503

and worked 🙂

IMG_7477

We just had Uben back! His usual laptop was in repair so he brought another one. We spent some time to install and setup everything 🙂

IMG_7487

Uben was told to create ultrasonic counter

 

IMG_7510

Uben likes to assemble things like this 🙂

IMG_7515

Too bad we didn’t had time to type in the code and compile it. Going to do it next week! 🙂

IMG_7519

Next week we will explore projects with micro servo! 😉

ProCodeCG Kids Regular Coding Class – Arduno/ESPectro Programming – 2 Sep 2017

Standard

Hello Saturday Coding Class 🙂

IMG_6964

Today more kids coming to continue their projects 🙂

Koosha brings his elevator project to the class 🙂

IMG_6990

IMG_6969

It has seven segment to display the floor number plus buttons to select up/down and a button for sounds too 🙂

IMG_6972

A very cool prototype 🙂

IMG_6973 IMG_6974

He duct-taped and glue-gunned everything inside the box 😀

IMG_6975 IMG_6976

IMG_6997

Koosha tests every components one by one.

IMG_7009

He chooses resistors very carefully 🙂

IMG_7010

There is something wrong with the seven-segment, Mama Ren helps and it works 🙂 But then Koosha decides to use LCD instead 😀

IMG_7019

IMG_7020

IMG_7013

the LCD, the breadboard, and the arduino is glue-gunned to the box 😀

IMG_7055

We’re testing the LCD and there are still some errors

IMG_7056

so Koosha won’t go until it works 😀

IMG_7057

Rezky is ready to continue another project: Automatic Pedestrian Traffic Light with Ultrasonic

IMG_6970

IMG_6995

Nafis is going to do the some project too

IMG_6994

So Rezky and Nafis got paired up to do the project together 🙂

IMG_6991

They learn and work better this way 🙂

IMG_7011

IMG_7012

Both test their own schematic

IMG_7015

IMG_7016

and help each other to debug errors 🙂

IMG_7017

Nafis’ works

IMG_7021

So does Rezky’s

IMG_7022

Both works! 🙂 They’re given another task to add LCD and display “Pedestrian crossing” plus count down for next week 🙂

IMG_7030

It’s been a long time since the last time Ren came to the class 🙂 Welcome back Ren and Mama Ren 🙂

IMG_6992

Ren is working on what Rezky and Nafis are working

IMG_6996

IMG_7018

IMG_7034

But the code won’t compile with ESPectro. So next time probably we will just use Arduino until we figure out what is wrong 😦

IMG_7038

Mama Ren is a very dedicated teacher

IMG_7024

She does some grading while Ren is coding 😀 Nice family 😉 ❤

IMG_7033

There will be more interesting project for next week! 🙂

 

 

ProCodeCG Kids Regular Coding Class – 26 Aug 2017

Standard

ProCodeCG always keeps commitment, even when there are only a few kids, we still open the class 😉

Today not many kids come to the class because our president, Bapak Joko Widodo will visit Bandung for a carnaval so many people stay off the street and prefer to stay at home to avoid traffic 🙂 *what really happen is that this early, the street is so clear, the traffic is so low 🙂

IMG_6536

IMG_6537

IMG_6526

Ozan is helping to prep the class 🙂

IMG_6518

Emma has arrived the earliest 🙂

IMG_6520

Emma shows her homework: to create a tic-tac-toe game with C

IMG_6521

IMG_6533

Emma has successfully created a random function to be the computer’s move

IMG_6538

The next problem is to create an algorithm to make the computer choosing the better move 🙂 *a complex problem but surprisingly Emma understands it very well

IMG_6542

Azriel 🙂

IMG_6522

Azriel has finished his Flappy Bird Game 🙂

IMG_6524

with several levels 🙂

IMG_6525

And he continues to create Agario Game 🙂

IMG_6531

IMG_6535

Done! 🙂 Next week he’ll be ready to invent a new game 😉

IMG_6543

Ozan is improving pedestrian traffic light button

IMG_6523

IMG_6527

instead activating by pressing a button, the traffic light for pedestrian is activated when the ultrasonic sensor sense an object

IMG_6534

The light was not working properly and Ozan learned to debug the code to make it work 😉 Next time we will create an ultrasonic gesture password 🙂

IMG_6540

Nanin 🙂

IMG_6528

She decided to create her new game not with Thunkable

IMG_6529

but with GameMaker 🙂

IMG_6530

Nanin is going to make a game to select animal category: pet vs wild animals 😉

IMG_6532

Nanin’s got lots of ideas 🙂

IMG_6539

but she has to deal with some image processing 😀 we will see the progress next week 🙂

IMG_6541

We leave the class earlier today (it is usually 9 – 12, today it’s 9 – 11). There are lots of cops all around the corners

IMG_6544

and also presidential security service everywhere 😉

IMG_6546

Feels much saver to have cops this many 😀

IMG_6547

See you next week 🙂

ProCodeCG Kids Coding Exhibition 2017 – 17 Aug 2017

ProCodeCG Kids Regular Coding Class – Arduino/ESPectro Programming – 19 Aug 2017

Standard

Hello Saturday 🙂 Working together setting up the class 🙂

IMG_6003 IMG_6004

Unexpected family reunion 😀

IMG_6005

OK let’s get started 🙂

IMG_6006

Abdillah got lots of things to do today because he’s going to a hackathon next week. We need to buy a gesture sensor, and before it arrives, we’re doing experiments with gyro

IMG_6007

We tried several devboards including Arduino Uno and Arduino Mega

IMG_6054

IMG_6063

But the problem apparently because we installed the incompatible libraries. We’ll find the correct ones and try again

IMG_6071

Hello Nafis welcome back 😉

IMG_6008

Nafis was going to create an ultrasonic counter 🙂

IMG_6016

But he got distracted with the avometer and started to learn how to use it. Plus learning how to count resistor values 🙂

IMG_6017

He was afraid he was going to electrocuted measuring the value of resistor LOL 😀

IMG_6018

Then Nafis started the project with the help of Rezky 🙂

IMG_6027

In ProCodeCG Kids Classes, we nurture the willingness to help and share with other kids. Kids are encouraged to teach other kids and share what they know 🙂 Good job, Rezky 😉

IMG_6028

Nafis’ messy but cool toolbox 😉

IMG_6029 2

Abdillah also helped Nafis to check the components because the devboard and sensors got heated up because the polarity was reversed 😀 And the ultrasonic sensor got burnt 😀

IMG_6040

And finally, it worked. Yeaaay Nafis 🙂

IMG_6050

Rezky was still debugging his ultrasonic sensor

IMG_6010

IMG_6039

IMG_6048

and finally it worked! Next is ultrasonic traffic light 😉

IMG_6020

IMG_6031

Awa! Was busy preparing for next Thursday’s Republic of IoT presentation 🙂

IMG_6012

Awa is improving his cat feeder. This is how it looks like. It uses servo to open and close the lid to pour out the food.

IMG_6013

Before, it uses button to activate the servo.

IMG_6014

IMG_6023

IMG_6026

And today Awa will use ultrasonic instead of button to activate the servo

IMG_6042

IMG_6044

Abdillah and Faris helped to set up the servo

IMG_6022

IMG_6073

And it worked nicely! Yaaaay, Awa is ready for the presentation 😉

IMG_6076

And then Awa was given a task to activate a micro servo

IMG_6015

doing it together with Abdillah 🙂

IMG_6019

And worked. And we’re going to create many projects with servo 😉

IMG_6021

Teamwork in class 🙂 Abdillah, Nafis and Rezky are working together to debug Nafis’ project 🙂

IMG_6034 IMG_6038

IMG_6045

This is ProCodeCG Kids Coding Class: leadership, teamwork and sharing 😉

IMG_6052

These ones are also teamworking to design something. Cinta is going to improve the ultrasonic traffic light. Probably with counter 🙂

IMG_6009

We got lots of ideas for projects, will be reporting soon! 😉
