Hi
I got a prblem.
I have numbers of phtoresistors,each of them I put it in voltage divider circuit to take this dividered voltage as an clock input to J-K counter 74xx76, this voltage increas when the the light decreas .I toke one photoresistor cct and step up my hand over it but the counter did not take it.
first ,I need somthing to put all these photo cct output together as one input to the counter.
secand ,I need to put somthing between the photo cct and the counter to regulate the voltage that came from the photo cct.
