Description: I ordered some H-bridge Integrated circuits and encountered so many roadblocks that I never ended up posting the video. This has been filmed over the past 4 months and recently I thought I would just take the time to print my own circuit boards so I can actually use these chips instead of getting rid of them. I still haven't made all that much progress on this project but I hope this video shows you just how many problems you may run into when working with hardware especially if you don't exactly know what you're doing. The ultimate goal is to have a fully automated battery testing system. You can place 10-20 batteries in a stack while stepper motors move the batteries through the system. Each battery will be connected to a constant current load of 1 amp and the Arduino will time the length of battery until discharge to calculate the capacity (last summer I built a discharge protection circuit). The Arduino will then store all information in an array and output live results on an LED display. For now my biggest concern has been getting the motors and mechanics to work correctly. Everything else should be a breeze.
