Hi,
yesterday I started my first attempt of connecting the dartboard to arduino.
The problem I found, was the delay reading the value from the dart when hits the dartboard.
I was using the keypad library. The arduino have to scan all ROWS and COLS, scan one by one.
The problem is, sometimes, when the dart hits the dartboard, the arduino can cacth it. (The circuit is closed and opened very fast). Other times doesn't.
If I'm not wrong, arduino must read the correct ROW and COL at the exact time that the circuit is closed, when the dart hited the board.
Any suggestion?
Thanks!
