HEADS OR TAILS GAME CIRCUIT


Posted on Feb 6, 2014

Designed to simulate by electronic means thetossing of a coin, the circuit is based upon a 4049 hex inverter IC, two of which are used. IC1a andIC1b are wired as an astable oscillator, which causes two LEDs D1 and D2 ‰ to alternate rapidly, at a frequency too high to be distinguished by thenaked eye. Both LEDs, therefore, appear to be constantly

illuminated. when the SPIN switch S2 is closed, this has the effect of freezing the display, and the LED, which was illuminated at the instantthat the switch was closed, will now be continuously alight. Opening the switch enables the oscillator once more. There is an equal chance of either LED lighting, and the circuit can be used in boardgames, for example, to choose which player will move first.
