An example arduino program to experiment I2C and OLED display. MCU periodically polls BME280 sensor every one minute, displays the reading on OLED, and prints to serial port. The default serial baud ...

The Arduino's program is set for I2C address 0x20 so it requires no change of the Z80-MBC2 firmware. It is recommended to pull the MCP23017 (which also uses address 0x20) to prevent interference on ...

In this tutorial we will use I2C communication between two arduino boards and send (0 to 127) values to each other by using potentiometer.

However, if you use an LCD module with I2C interface, you only need 2 lines to process the display information. Now a days, it is not necessary to buy an expensive I2C LCD for this task because ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino … ...

This project demonstrates how you can build a real-time clock (RTC) with a temperature display using Arduino, DS3231 RTC and SSD1306 display.
