DIY Arduino Transistor Tester | Test NPN & PNP Transistors Using Arduino Nano




In this video, I will show you how to make a transistor tester using an Arduino Nano. This project will help you easily test NPN and PNP transistors and identify their condition. The Arduino Nano checks the transistor type and displays the results on an OLED screen. You can also use this project to determine whether the transistor is working properly or faulty. Watch the full video to see step-by-step instructions and complete code.

🔧 Components Required:

Arduino Nano

I2C Display
