How To Build A Battery Tester

Do you have some rechargeable batteries lying around that need a capacity check? Today, we’ll take an Arduino Nano and a few other electronic parts to build a AA battery tester that will give us fairly accurate “real world” readings on NiMH batteries. This little device will come in handy for the next project on the list, so be sure to subscribe for more how-tos!
