Dear sir,
i send a file of proteus there i show the diagrame of circuit that what i am trying.
Ok i explain you in a word,i want to use 16f677a, 2 BCD Thumbwheels for setting the input numbers that what i require the numbers of count to the help of proximity sensor,for suppose i set the number on BCD Thumbwheelswitch 40 or45 or50 or 60 whatever and give the pulses to proximity sensor to the pic input, while when the pulses will reach at taget numbers there i have set on BCD Thumbwheel swithch, so the output will go high and there we can also use relay.

My english is very poor so please take care.

Thankyou
