TEN_STEP_COUNTER_FOR_CONTROLLERS

Published:2009/7/12 22:29:00 Author:May | From:SeekIC

A 4017 divide-by-10 counter IC is the heart of this simple 10-output controller circuit. Two gates of a 4011 quad two-input NAND gate IC are connected in an astable oscillator circuit to clock the divide-by-10 counter U1. The step time is set by R5. With the RUN/RESET switch in the RUN position, U1 takes 10 equal steps and then stops. Momentarily switching S1 to RESET starts the cycle over
