The Voltmeter Soldering Kit is an educational kit I developed to help teach THT soldering. In addition to being a great learning tool, the kit works as a voltmeter once it is complete!
When students no longer need their voltmeter, they can also remove the 328P and put it into a secondary board, to use as an Arduino.
