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 Synchronized Programmable Timer 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 […]
Delay based Motor Speed Controller Circuit – Timer Controlled
In this post I have explained a delay OFF adjustable motor controller circuit so that the motor can be assigned a fixed predetermined operating time, or delay OFF time. The idea was requested by Mr. Cribey Technical Specifications I really like your website. It is very helpful for so many people. I am trying to […]
How to Make an Industrial Delay Timer Circuit
In this post we’ll study two simple externally triggered timer circuits for two different application needs, the ideas were requested by Mr. Alan and Ms.Stevanie Circuit Request#1 I only wish I understood electronics as you do. Would you please help me with a simple timer circuit which would be adjustable for up to 30 seconds […]
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 […]
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 […]
