Want to test LEDs quickly and efficiently? This DIY LED Tester uses a 12-0-12 transformer, bridge rectifier, capacitor, and a 300Ω 5W resistor to test almost all types of LEDs, including SMD LEDs on DOBs.
🔹 Circuit Components:
✅ 12-0-12 Transformer
✅ Bridge Rectifier & Capacitor
✅ 300Ω 5W Resistor
✅ Multimeter Probes for Testing
✅ Digital Voltmeter for Voltage Measurement
💡 Bonus Modification: I’ve also added a digital voltmeter to measure the LED voltage in real-time!
📌 Key Features:
✔ Works with almost all LEDs
✔ Ideal for SMD LEDs on DOBs
✔ Easy to build and test
