u8x8 example on Arduino UNO R3 with a 128x32 I2C OLED Display

Playground for u8x8lib on a I2C 128x32 OLED display based on SSD1306 drivers, which I bought on eBay.

Technologies used:

• u8x8 library from u8g2 project u8x8 reference
• Atom IDE with PlatformIO
• Fritzing for drawing a schematic

This repo also includes an examples folder of:

• how to debounce a momentary button in an interrupt
• how to debounce a momentary button in main loop
• ..an alternative of the delay() function, how all we know it pauses the code in main loop by using an interrupt routine..
• how to pass a function as a parameter in a function
