    Does Anyone pleqase know how to clear a counter. I built a light chaser, anytime i switch it on it starts counting form the last L.E.D it stopped at, at d previous count(i.e before i switched it off). I would like it to start counting from '0' when i put it on. Thanks

    Which decade counter are you using?

    There are quite a few different decade counters in both 4000 series and 74xx series IC's.

    Remove the RESET pin connection to ground.

    Connect a 47k resistor from the RESET pin connection to ground, and a 1uF capacitor between Vdd and the RESET pin.
