Simple and useful project, thank you... What is the value of the current limiting resistor? Can a digital voltmeter be attached to read the voltage of the tested LEDs?
Yes you can attach a voltmeter to it, I found this usefull on minuscule led's to tell where is the positive and negative , on those smaller than 1mm is really hard to see it with the naked eye , but after I check with this I know exactly how to place the new led

I would like to know the value of the limiter resistor that's inside the battery box.
Seems Like Alot Of Trouble
& Rigmaroe To Make An Led
Tester. When All you Need Is
2 AA Batterys To Test Led's.
