The Velleman VM147 offers a very practical solution for counting parts, people, score keeping, etc. using the on-board push buttons or by external pulses. Open collector output activates when user preset value matches count.
The open collector output (see Help Sheet for more info) can be used to drive a small load or trigger our 3156 relay board or the 3141 delay timer board.
