So I am a complete newbie on all of this but what I am trying to do is build a “counter for my son who plays lacrosse. Basically I was thinking of using an arduino Uno and a knock sensor and somehow attach it to a sheet or two of plywood in the shop and have it connected, somehow, to a 3 digit counter so it could show him how many he has done. It would need to have a reset button and all of that. Anyone have any help????
By the way, when I say I am a newbie, today is my first day ever laying hands on an arduino.
