An Arduino microcontroller is used in this project to create a versatile timer. Unlike a traditional two step timer with separate outputs, this circuit focuses on a single output that cycles through two distinct states, each of which has an adjustable delay to allow for flexibility in controlling different applications.

Simple Power ON Delay Circuit
A simple power on delay circuit using IC 555 establishes a delay between power supply and circuit activation. When a trigger is received, the IC 555 runs in monostable mode, which causes it to produce a single output pulse for a predetermined amount of time. The timing network that establishes the delay time is made […]
AC Power Outlet with Timer Circuit
Consider a standard plug that plugs into a wall socket and has a timer built right in, like a control panel. This is known as a timer plug or outlet timer. Another appliance can be plugged into it. The integrated circuit, especially a 555 timer, is the timers little brain. That is the cool part, […]
Simple Automatic Power Delay OFF Circuit
This Automatic Power Delay OFF Circuit is like a friendly reminder to turn things off. You can set it up with your device, and after a certain amount of time has passed like 1 hour, 2 hours etc. the circuit automatically cuts the power. This is useful for things like leaving a nightlight on for […]
Simple 220V Time Delay Switch Circuit with Triac
Imagine a smart switch for your appliances with a built in waiting time. This 220V time delay switch circuit is like a fancy power button that waits a bit before turning on your lights, motor or other device. You can set it to wait a few seconds or minutes after you turn it on. The […]
Simple Timer Circuit with Alarm using IC 4060
This circuit is like a mini stopwatch with a built in buzzer. It uses a special chip IC 4060 to count the seconds like a tiny clock. You can set the timer for a certain amount of time, and when that time is up, the buzzer goes off to remind you, just like a kitchen […]
