Timer Circuits with Auto Pause and Memory During Power Failures
In this post we try to investigate a couple of innovative solutions which could be used for pausing the counting process of a timer IC during power failures, and also restart the process when mains is restored, ensuring a continuous functioning of the timer without errors. The idea was requested by Mr. Arun Dev. Technical […]
Input Trigger Synchronized Monostable Timer Using IC 555
Here we study a simple IC 555 based monostable circuit whose output monostable time duration starts only after the input trigger is released thus making sure that the trigger ON time duration is added with the monostable’s pre-programmed ON time duration. The idea was requested by Mr. John Brogan Technical Specifications I would like to […]
Digital Clock Activated Water Level Controller Circuit
An automatic clock time triggered water level controller circuit which responds to a real time clock input is discussed in the following article. The design also includes a water detection stage which makes sure the initialization takes place only in the presence of water in the tank or the pipe. The idea was requested by […]
Programmable Temperature Controller Circuit with Timer
Here I have explained about a circuit configuration which produces adjustable sequential timing outputs for controlling a heater device through a simultaneously sequencing temperature controller circuit which can be also pre-programmed for acquiring the desired temperature levels across the sequencing time slots. The idea was requested by Mr. Carlos Technical Specifications I’m Carlos and I […]
Programmable Diesel Generator Timer Circuit
In this post I have explained a simple yet accurate programmable diesel generator timer circuit which can be used for achieving discretely programmable ON/OFF timing sequence for the connected diesel generator set. The idea was requested by Mr. Raj Kumar Mukherji. Technical Specifications Happy new year and hope you are fine. There is a request […]
