One of the most widely used and adaptable integrated circuits in electronics is the IC 555. It can function in a number of modes, including bistable, astable and monostable configurations. In this project, we will use the IC 555 in monostable mode to build a easy DIY timer alarm circuit. With this circuit, you may […]

Simple 60 Second Timer Circuit using IC 555
A timer circuit is a flexible instrument used to regulate the timing of an event or process in a variety of electrical tasks. The 555 timer IC, a popular integrated circuit for timing and oscillator applications, is utilized to create the Simple 60 Second Timer Circuit that is being presented here. When a push button […]
Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment
This project for Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment uses Arduino microcontroller to make simple timer. Not like normal timer with two outputs as this one uses only one output. It switch between two states. And each state have delay which we can change for different use. Circuit Working: Parts List: […]
Power ON Delay Circuit
Power ON Delay Circuit using IC 555 give time gap between power ON and circuit starts. When trigger comes, IC 555 work in monostable mode and give one output pulse for set time. Resistor R1 and capacitor C2 make timing part for delay. Output stay low with circuit OFF when capacitor is charging. When power […]
AC Power Outlet with Timer Circuit
In this AC Power Outlet with Timer Circuit think about a normal plug goes in wall but this one have a timer built-in like small control panel. This is called a timer plug or outlet timer. We can plug other device into it. Inside, small chip work like a brain and it is called 555 […]
Automatic Power Delay OFF Circuit
This Automatic Power Delay OFF Circuit is like small helper to remind us to turn OFF things. We can connect it with our device with the time frame like 1 hour, 2 hour as it stops the power by itself. It is very useful if we want to keep nightlight ON for some time or […]
