How do I build a circuit that emits a loud beep along with a bright flash?
I want to build a circuit that at the press of a button will emit a loud short beep (1khz would be good) and at exactly the same time a bulb would make a quick bright flash ( a camera flash would be ideal). I want to use this device to help me synchronise my video camera picture with sound recorded on another device. In effect this circuit is a clapper board! Can anyone point me in the right direction, what components would I need? Many thanks.
