This paper shredder bin monitor is an easy Arduino project for beginners to get into. It uses an ultrasonic sensor, which is placed inside the bin, to detect the trash level.

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino. Use cron jobs on Linux to schedule ...

The Saturn’s electronics aren’t sophisticated enough to implement a lean burn system simply, and so [Robot Cantina] did what any of us might have done: hacked it in with an Arduino.

Also note that the Theremin demonstrated here is a stripped-down (and tricky) version of the far-famed proximity-controlled musical instrument – the key difference is that it employs a cheap light ...

Arduino Lint is an easy-to-use, yet powerful, command line tool, focusing on the structure, metadata, and configuration of Arduino projects, rather than the code itself.
