5 projects best suited to an Arduino, not a Raspberry Pi. Story by Patrick Hearn • 3mo. A n Arduino is a microcontroller — a single board designed to control something and perform a specific task.

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

DIY Projects: Automate and Innovate 1. Home Automation with Raspberry Pi + Arduino. Goal: Control lights and appliances using relays, sensors, and a web interface. Components Needed: Raspberry Pi 4.
