These displays use I2C or SPI to communicate, 2 to 5 pins are required to interface.
These displays use I2C or SPI to communicate, 2 to 5 pins are required to interface. Arduinos have dedicated I2C-pins that are used by the Wire-Library. Like A4(SDA), A5(SCL) on a UNO or 20(SDA), 21(SCL) on a MEGA 2560. Look out for the I2C-pins of your board.
