Metal Detector Circuit with BC547 Transistor | Simple & Powerful #shorts #electronics #diy

Build a simple yet effective metal detector circuit using BC547 transistor! 🧲 This DIY electronics project uses a handmade coil and basic components to detect nearby metal objects. Perfect for beginners, students, and hobbyists, this circuit runs on a 9V battery and is easy to assemble at home. ⚡ How it works: The BC547 transistor amplifies signals from the coil (100µH), allowing the circuit to detect changes when metal comes close. The buzzer alerts you instantly! 🛠️ Components Used: BC547 Transistor 20 Turns Coil (≈100µH) 2.2pF Capacitor 4.7nF Capacitor 100nF Capacitor 50K Potentiometer 9V Battery Buzzer 💡 Try adjusting the potentiometer for better sensitivity! #metaldetector #electronics #diyproject #bc547 #transistor #circuit #arduino #tech #shorts #engineering #maker #electronicproject
