The LED Brightness Adjuster Kit from Sparkfun is a must-have tool for any hobbyist or professional who frequently works with LEDs. It's an innovative solution for the common problem of inconsistent LED brightness. This kit allows you to test and adjust the brightness of your LEDs, ensuring that they all shine with the same intensity. The adjuster is compatible with different sizes of LEDs, both SMD and through-hole, providing you with flexibility and convenience.
The LED Brightness Adjuster Kit is designed to fit into the power rails of a breadboard, allowing you to stack up to 10 boards next to each other. Each board can accommodate one LED. A 10k linear potentiometer is included for adjusting the LED brightness, and a 100 Ohm resistor is in series to protect the LED from burning out. Silkscreen labels around the potentiometer indicate the approximate resistance, and there are test points "R+" and "R-" for measuring the exact resistance with a DMM.
The kit includes the PCB, a potentiometer, a 100 Ohm resistor, and headers for connecting into a breadboard. However, LEDs are not included, as the idea is to test your own. The kit does not come pre-assembled, so you'll need to use a soldering iron. This makes it a great learning tool for anyone starting to learn electronics, providing a hands-on introduction to soldering and Ohm's Law.
