Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino.

Using hardware I2C on an ESP32? Do you need to connect multiple I2C devices with the same address? Normally, you wouldn’t be able to do that without extra parts, but on the ESP32, [BastelBaus… ...

Aside from these components, you'll also need an I2C module to convert your LCD into an I2C device (so it uses fewer pins), a motor driver for your fan, a breadboard to hold the components ...

Arduino has created a Renesas RA4M1 microcontroller board in its Nano form-factor. Called Nano R4, it follows the Uno R4, the first Arduino to use the RA4M1. “Whether you’re working on a connected ...
