I have a LED digital counter which I can not get to work.
I have tried to put 12v to pin 1 and 5 but nothing happens ..
Is there anyone who can help to draw how I should do?
I need it to start time with a current signal and that's it .. maybe a reset button ..
Its a pulse counter, not a clock.
Power it up on pins 1 and 5 and hook up a push button to pins 2 and 5 and it will count how many times you push the button.
