This is going to be difficult to describe…so Ill do it in point form to hopefully keep it simple:
-I require a circuit that runs on dc (any voltage)
-Its for a game
-I have a series of 5 pegs
-The idea is that 1 peg is randomly selected by the circuit to be “active”.
-when the “active” peg is removed, a relay closes.
-eventually, all pegs are put back in place…the relay opens
-a button is pressed, to once again select a random (and unknown) peg…and so on
I was thinking something along the lines of a 555 driving a 4017, driving a modulated series of infrared leds mounted on the peg sleeve. A infared receiver is mounted opposite the emitter, with the peg body normally blocking the Infared illumination. Once that peg is removed on the “active” emitter/receiver, it activates a relay.
The pegs are all returned into their sleeve, the button is pressed, AND the 4017 stops on another transmitter/receiver pair…and so on.
I was only thinking using infared leds, so they will not be bothered by ambient light.
So whatcha think?. I don’t really want a cuircuit that runs on a Microcontroller, I prefer good, old fashioned Ic’s.
Thanks in advance.
