I am pleased to present what I have been working on today - an LCD (Liquid Crystal Display) setup using I2C with three different microcontroller boards. It was pure curiosity leading the way, pushing ...

This small project is for scanning for I2C devices on the I2C bus of a microcontroller. I initially used the I2C scanner from the Arduino Playground as a basis. I ...

Adafruit has this week announced the arrival of the new Arduino compatible TCA9548A I2C Multiplexer to their online shop, which is now available to purchase priced at $6.95. The latest breakout board ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...

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 ...

[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 will ...
