The use of current regulator in a LED tester is shown in this project which will allow determining the exact voltage and current to supply a LED. Testing a LED comes in two ways. First is by plugging ...
This circuit can be used to test up to three LEDs at once, connected in series. You can easily increase that number by using a higher supply voltage. If you do so, you should allow 2.7 V for each ...
