Can you help me?
I am constructing a new type of children's toy and need some help.
I have four switches situated in a circle each located at a cardinal point. A rotating arm spins in the centre. When the arm rotates to become situated in front of a switch, I require the switch to be turned on, then as the arm passes to be turned off. The rotating arm will spin at fluctuating revolutions. The end of the arm and the switch are very close to each other, separated by only a small fraction of an inch (1/16th +/-).
I really do not want a mechanical solution, basically because of friction. I considered some sort of triggering device like infrared or laser, if that would be possible, but of course the action must not interfere with any of the other three switches.
Can anyone can offer me a solution - a circuit, or whatever? I would be so extremely grateful.
Last point, I am not electronically trained or efficient and am barely able to solder two wires together.
Thank you very much
John Simpson
