This delay off lamp timer circuit will automatically switch OFF a connected lamp after a predetermined time has elapsed. This time delay can be adjusted with a variable resistor or a potentiometer. The circuit is initiated by pressing a push button, which causes the connected lamp to switch ON. The lamp will continue to remain […]

Audio Delay Line Circuit – For Echo, Reverb Effects
An audio delay line is a technique in which a given audio signal is passed through a series of digital storage stages, until the final audio output is delayed by a certain period (usually in milliseconds). When this delayed audio output is fed back to the original audio, it results in an amazingly enhanced audio, […]
Mains High Low Voltage Protection Circuit with Delay Monitor
In this post I have explained an upgraded version of my previous mains 220V/120V high-low voltage cut off protection circuit which now includes a delayed restoration of power for the load with 3 LED power status indicators. The idea was requested by one of the dedicated members of this website. Circuit Objectives and Requirements Main […]
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 […]
Blinking an LED with Delay – Arduino Basics
Here I have explained the bare minimum code for compiling an Arduino and also the method of blinking an LED using an Arduino board. Learning the Bare Basics Here we discus and try to understand the fundamental minimum code that one would need to compile an “Arduino Sketch” which consists the setup()method and the loop()method. […]
