Introduction: Battery Clip LED Tester.

have you ever put together a circuit and after finishing you find your LED doesn't work? well with this Instructable that will never happen again! I present to you the Battery clip LED tester.

Step 1: Components:

Components:
female header pins
1k resistor
perfboard
9v battery clip

Tools:
soldering iron
solder

Step 2: Header Pins

solder your header pins onto a piece of perfboard, sorry about the lack of a good photo.

Step 3: Resistor

solder the 1k resistor to the header pins.

Step 4: More Soldering!

Solder the leads of the battery clip to the resistor and the other header pin.

Step 5: Your Done!

well done you now have a functioning LED tester!

You could even adjust the circuit and use it to test transistors.

Hi

Sorry, i took that down ages ago, i saw that make: had made a video on it and i didn't want people saying that i'd copied their idea.

Here's a link to their wepage on it, it's much better than mine was anyway. :)

What a neat little evening project. I've added a push button to the thing.
