Here is a simple tester for Hobbyists. This LED Component tester can test the integrity of electronic components from resistors to ICs before soldering. It reduces the job of testing the components ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, ...

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 ...

The simple Diode and LED Tester presented here costs under £5 to build (including all components, the battery and a cheap case) and will indicate the polarity of almost all types of LED and other ...

The BTS256-LED Tester measures luminous flux, illuminance, color quantities and spectra of individual LEDs and traditional light sources. Larger size light sources can be measured by attaching the ...
