COIN_TOSS_CIRCUIT

Published:2009/7/14 1:51:00 Author:May | From:SeekIC

Shown is a CMOS coin-toss circuit that works well and can be built with a single 4011 or 4001 CMOS IC.(Note that the IC pin numbers in the diagram apply for both the 4001 and the 4011.) Two gates form a clock, and the others make up a bistable multivibrator. With this circuit ,It is necessary to adjust the 10,000-Ω potentiometer （R3） for a 50-percent duty cycle. If you don’t have a scope to do this, simply measure the direct current flowing through each LED while adjusting R3. When the same current level flows through each LED, the clock will be adjusted for a 50-percent duty cycle.
