☢🌫 How to Control Fan Speed with Arduino Using PWM and a Potentiometer
Controlling the speed of a fan using Arduino is a great way to learn about PWM (Pulse Width Modulation) and analog input. This project is simple, powerful, and forms the basis of temperature control systems , ventilation , robot cooling , and more. Whether you're building a DIY smart home setup or a robot with cooling , this tutorial will teach you how to adjust fan speed in real-time using a potentiometer . 🔧 Components Required ✅ Arduino Uno (or compatible board) ✅ DC Fan (5V or 12V based on setup) ✅ Potentiometer (10kΩ) ✅ NPN Transistor (e.g., TIP120 or 2N2222) (optional for higher power fans) ✅ Diode (1N4007 for back EMF protection) (optional) ✅ Jumper wires & Breadboard 🛒 Buy all components from Plysmotix.in – Fast shipping across India! 📲 Bonus: Download the Plysmotix Android App Want circuit diagrams, live tutorials, and mobile Bluetooth control? 🎯 Download the Plysmotix App and: Get interactive guides Shop components directly fr...
