Walking bitmap on 0.96 inch 128X64 I2C OLED x Arduino Nano

Implement walking bitmap on 0.96 inch 128X64 I2C OLED x Arduino Nano V3.0 (ATmega328 5V), using u8glib library.


(Refer to te post "Hello World 0.96 inch 128X64 I2C OLED, on Arduino Uno, using u8glib library" to install the library to Arduino IDE)

Connect the 0.96 inch 128X64 I2C OLED to Arduino Nano:

GND - GND on Arduino Uno
VCC - 5V on Arduino Uno
SCL - A5 on Arduino Uno
SDA - A4 on Arduino Uno
