Simple Digital Clock using LM8650 IC Circuit

Last Updated on September 30, 2024 by Swagatam 66 Comments

largedigitalclockcircuit

The digital time clock explained here is a circuit which most electronic amateurs would love to make. You might have heard about digital clocks made from clock ICs such as the popular LM8361, MM5387 etc but these ICs could be today quite obsolete and/or complex to build. Circuit Operation The present design is much easier […]
