Figuring out how to wire a raspberry pi to solar with battery and a Arduino to power it off at night and on in the morning. Just figuring out how to use a relay to control power to the pi. Figured out how to program the Arduino that was fun having it toggle an led on and off. Keep burning myself with the soldering iron and maybe next I should learn about breadboards... electronics are fun
