This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, allowing the Arduino to control ...

This project controls a relay module using an Arduino, providing both automated timer-based operation and manual override functionality via a button. The system is designed for applications where a ...

Fig. 1: Author’s prototype for Smart Electric Iron Circuit and working As shown in Fig. 2, the circuit built around Arduino Uno Board1 includes single-changeover relay module MOD1, MPU6050 module MOD2 ...

The resistance value varies per manufacturer, but 220Ω per leg is a safe bet. Tip: learn how to power light bulbs using Arduino with a relay module. What You’ll Need If you’re ready to get started, ...

He put it all together on proto-board, although soldering the FM radio module was a bit tricky. The Arduino code is quite simple, and available for download (zip file).

If the stench from your cat's litter box is a bit too much for you to take, consider rigging together an exhaust system using a 120mm computer case fan, a 12vdc power supply, 4" flexible dryer ...
