Now on to our post. Today we'd like to direct your attention to a new tutorial written by our testing guru Pete Lewis. Pete found a great hack to quickly and easily test LEDs using a pair of fast-switching tweezers.
Pete used an Arduino Pro Mini, some multimeter tweezers, and a few other pieces to create a quick solution for testing out LEDs you have laying around. Is it red? Is it green? Is this the LED that I accidentally destroyed? These tweezers make answering these questions easy. Here is the wish list with the parts you'll need to build your own:
Check out the full tutorial to see how to put together a pair of your own. Happy hacking!
