Driving the Plunger (part 2)

▤ Summary

While having a button on board was a handy thing to have during the testing, I really wanted an external connection for a foot pedal. Not only are they easy and cheap to get, but theyre the only practical way to trigger something while keeping both of your hands free. I did play with some other microcontrollers out there, but my pipeline and knowledge are so heavily skewed toward PIC that I always select it for projects like this. It took me a bit of troubleshooting to notice I messed up Vref voltage divider and that was causing any load to trip the current limit function on my motor driver. As I already soldered the whole board, I had to unsolder the OLED to reach resistors underneath and place a bodge wire.
