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 ...

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 ...

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 ...

[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, ...

Every new Particle project is composed of 3 important elements that you'll see have been created in your project directory for RGB_LED_Tester. This is the source folder that contains the firmware ...

LEDs are used everywhere these days, not just as on/off indicators any more but now also as a source of light. Before you mount an LED in your circuit it would be nice if you could first check whether ...
