Re: new project: LED tester

 

Greetings,

Thank you Bruce W8BH for sharing your LED Tester project with us.

I know that I, for one, am very interested in building this project.
My current LED tester consists of:
a bench power supply,
two DMMs; one to measure Voltage, and the other to measure Current,
a Resistor Substitution Box,
a breadboard where it is all connected together and where I insert the LED.

It works great, but it is rather large. 8^D

Here is the documentation for an LED tester.? For $20-25 in parts, you can build a battery-operated, microcontroller-based device for characterizing that box of assorted LEDs.? ?It shows you the current and forward voltage at varying resistances.? I am still working on the documentation.
