It has an image sensor and a microcontroller with pretrained ML models that use computer vision to spot faces. There's a detailed developer guide available, but this project has sample code that shows ...

[Marcus] has written up his experiences using the AD7746 capacitance sensor. He used the SparkFun breakout board in conjunction with an Arduino. The available Arduino code wasn’t that great s… ...

Arduino code for detecting basic hand gestures using HC-SR04 ultrasonic distance sensor array. This code utilizes three HC-SR04 ultrasonic distance sensor modules placed linearly with a fixed distance ...

If you have an Arduino that can act as a keyboard for a PC, the code almost writes itself. [Rootsaid] uses a specific library for the PAJ7620 and another — Nicohood — for sending media keys.
