We are getting about how to make the digital clocks more accurate and precise even at varying parameters like temperature and humidity. Generally, in the market, if we go for buying the RTC module we will find the DS1307 module more simply. As DS1307 module is more prone to external temperature variation because it uses an external crystal oscillator circuit as a result the accuracy of the timekeeping changes. While designing a LED board for my college kec.edu.np, I suffered from a time accuracy problem. After a few days, time…

programmable digital timer circuit

The project “programmable digital timer circuit” presented here can be used for setting time intervals in the range of 1 to 99 minutes. The circuit of a programmable digital timer does not use large resistors or capacitors to obtain the timing interval. Instead, it uses the 50 Hz mains frequency as a reference. The main frequency is fairly accurate for this application. The main frequency is shaped up by Schmitt-trigger gate N1 to obtain a square wave. This 50 Hz square wave is divided by IC1, IC2, IC3, and IC4.…
