Arduino and OLED based Cellular Automata

This project tutorial uses an I2C 128×64 OLED to display a tiny cellular automata powered by Arduino Nano.

Step 1: What You Need?

1 x Arduino Nano (can be Arduino UNO as well)
1 x OLED I2C 128x64
2 x Mini Breadboard 
1 x Arduino Mini USB Cable
Male-to-Male Jumper Wires 

Don't have components? Don't worry. Just click the component's name. 

Step 2: Build Your Circuit.

So hook up the Arduino and OLED LCD to the breadboard and start wiring.

  Arduino —– OLED

• 3.3v — VCC (pay attention to your OLED voltage requirements)
• GND — GND
• A4 —SDA
• A5 — SCL

Then I attached both breadboards back to back and created a small TV.

Step 3: Upload Code To Board.

In order to facilitate (and make it possible) to play with the OLED display, we will be using 2 libraries from Adafruit. If you don’t know how to add libraries please visit https://www.arduino.cc/en/Guide/Libraries

Adafruit GFX library which will be used to handle all graphics and text displayed on the OLED https://github.com/adafruit/Adafruit-GFX-Library

Adafruit SSD1306 library which basically is the driver for our OLED. This library works only with OLED SSD1306 128×32 and 128×64 https://github.com/adafruit/Adafruit_SSD1306

On line 51 with code,

display.begin(SSD1306_SWITCHCAPVCC, 0x3C); //initialize with the I2C addr 0x3C (128x64)

the address, which is the 0x3C might be different. I searched for the most obvious and tried a few before getting it to work.

Step 4: Test Your Circuit.
