A minimal example that demonstrates how to drive an SSD1306 I2C OLED display from an Arduino UNO R4 using the Adafruit SSD1306 and Adafruit GFX libraries. The project prints a few lines on the OLED ...

SPI - Serial Peripheral Interface (SPI), sometimes called a 4-wire interface, is a serial synchronous data transfer interface. Unlike I2C and UART, SPI requires more signals to operate but can operate ...

For several microcontroller projects, the integration of a minuscule display panel can be handy to show relevant information. For example, information gathered by an external sensor module. Here we ...
