Digital Clock Synchronized Programmable Timer Circuit

Last Updated on May 13, 2020 by Swagatam 8 Comments

set reset latch circuit

I have already discussed one programmable timer circuit in this blog earlier, the circuit involves the IC 4060 for generating the basic oscillations which is further used for generating the required time intervals, however this cannot be synchronized with an external clock. The following circuit was requested by Mr.Amit, here the concept makes use of a clock for acquiring the required base timing […]

Simple Delay Timer Circuits Explained

Last Updated on January 2, 2024 by Swagatam 673 Comments

In this post I have explained the making of simple delay timers using very ordinary components like transistors, capacitors and diodes. All these circuits will produce delay ON or delay OFF time intervals at the output for a predetermined period, from a few seconds to many minutes. All the designs are fully adjustable. Importance of […]
