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

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 Coding Exhibition 2017 – 17 Aug 2017

ProCodeCG Kids Regular Coding Class – ESPectro Programming – 5 Aug 2017

Standard

Hello! This is our regular thing on Saturdays 🙂

IMG_4985

Vian surprisingly told us he wants to learn Arduino/ESPectro Programming instead of GameMaker and Minecraft 🙂

IMG_4974

He learned to make an LED blinking 😉

IMG_4958

IMG_4959

and then 2 LEDs

IMG_4969

and then 3 LEDs

IMG_4980

and then because we’re out of breadboards then Vian learned how to make RGB LED works 🙂

IMG_4981

Rezky got a new LCD I2C and ready to test it

IMG_4944

IMG_4951

Yea it worked 🙂

IMG_4952

Rezky learned to create some simple custom char

IMG_4956

and also lots of sets of custom chars 🙂

IMG_4966

So did Ruben, he had just got a new LCD I2C

IMG_4946

he did the wiring and prepare to test it 🙂

IMG_4949 2

while we’re installing some libraries, he drew 🙂 amazing 🙂

IMG_4953

or put everything inside his toolbox on a breadboard 😀

IMG_4961

or lay down for a while 😀

IMG_4972

ok Uben, the library is ready, let’s compile 😉 Yes it works! 🙂

IMG_4965

Ruben learned how to display text on the LCD

IMG_4973

and also how to put a smile on it 🙂

IMG_4987

then given the task to put a sad face 😉

IMG_4988

Ozan was really busy making an ultrasonic sensor work 😉

IMG_4948 2

IMG_4957

IMG_4977

and finally it worked 🙂

IMG_4978 2

The LCD is showing the number it is counting *it was dimmed because we use 3,3V instead of 5V (the 5V is used to power the ultrasonic sensor)

IMG_4979

Yaaay, awesome work Ozaaaaan 😉

IMG_4983 2

Nadine wanted to learn Arduino/ESPectro programming too 🙂 Capt. Faris helped her to get started 🙂

IMG_4950 2

Nadine is very interested to learn about components and devboard 🙂

IMG_4960

IMG_4962 2

She learned how to make a LED blinking (just like Vian)

IMG_4975 IMG_4976

Learned some debugging with Capt. Faris

IMG_4982

and then learned to blink more LEDs 😉

IMG_4984

and also RGB LED 🙂

IMG_4990

Proud! Good job Nadine! *she can’t wait to have her own ProCodeCG Kits next week 😉

IMG_4991

Capt. Cinta examining the ProCodeCG Big Toolbox to get some idea what to create 🙂

IMG_4942 2

It’s so much fun today like always 😉

ProCodeCG codeMeetUp() #108 – Exclusor – CryptoEconomics

Standard

Today, we had Founder of Exclusor, Tata Tricipta, sharing about CryptoEconomics on ProCodeCG codeMeetUp() #108 🙂

About Exclusor (from the WhitePaper):
“Exclusor introduces a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. Reducing energy consumption and high cost in block creation, thus lowering the customer fee unlike current blockchain transactions. This can be achieved by implementing new consensus algorithm and deploying consortium network model.”

IMG_4273

We set up the room while waiting for more people to come 🙂

IMG_4274

This is a very recent topic involving cutting-edge technology 🙂
