Battery Polarity Tester: A DIY Electronic Project
Battery Polarity Tester: A DIY Electronic Project
Hi friends, today we are going to create a DIY battery
polarity tester which is a simple and useful electronic project. With the help
of this battery polarity tester you can find the positive and negative
terminals of a 12v battery. I have used a pieces of PCB for this project but if
you don’t have a PCB, you can use a blank PCB or a piece of wood or cardboard. You
will need the below electronic components for this project:
- Red LEDs: two pieces.
- Yellow LEDs: two pieces.
- 1kΩ Resistors: two pieces.
- Wire with alligator clip: two pieces.
- A piece of blank PCB.
Solder all the above electronic component on a piece of CB
according to the above circuit diagram. And you are done.
