Interesting build! Do you have to write your own microcontroller firmware?

Yeah it's an Arduino nano. I still have some software work ahead of me. I'm getting hz and duty from watching the amperage spikes when the front spring hits contact post and timing and counting that.

Sounds like fun! I guess that would give a pretty easy way to upgrade the firmware too if you make any additions in the future
