Light circuit that flashes an LED once when a light is detected?
I'm kinda a new to circuits and i would really like your help guys! I'm trying to create a circuit that flashes an LED once if light is detected. I also want it with a 2-3secs delay which means after the LED flashes once the circuit turns off for 2-3secs (even if light was detected after the led flashes it will not flash again until after 2-3secs). Can i use a 555 timer to do so...and if yes how is the setup.
