The CD4541B is a CMOS programmable timer IC, and we use it where long delay interval is needed for a load, and also for jobs like frequency division, or timing pulse work. And all this happens with only just a few outside parts, not much around it. With ordinary IC 555, when delay becomes too […]

2 Best Long Duration Timer Circuits Explained
In this post I have explained how to make 2 accurate long duration timer circuits ranging from 4 hours to 40 hours, which can be upgraded further for getting even longer delays. The concepts are fully adjustable. A timer in electronics is essentially a device which is used for producing time delay intervals for switching […]
