I have got to laser beams / receivers working correctly. When beam is split i get 5 volts very clear and 0v when beam is in tact.
I want to use one of the beams as my starting point so when it is broken it starts a counter etc.
Then when the second beam is broken it stops the counter.
I have put this on the forum before but didnt have much luck. Can someone give me a circuit diagram for this or explain it to me. I have heard about using flip flops etc so all help appreciated.
