Unlike a standard wall outlet, this AC Power Outlet with Timer Circuit incorporates a built-in timer; as a result, it functions as a timer plug, also known as an outlet timer. Also, we can plug other device into it. Furthermore, a small chip called the 555 timer acts as the brain of the circuit, also […]

Automatic Staircase Light Circuit
Automatic Staircase Light Circuit turn ON light when someone uses stairs and after some time it turn OFF by itself automatically; also it help keep home safe and saves electricity. Circuit Introduction: Regular stair lights: We turn the system ON and OFF manually using switches at the top and bottom; however, sometimes people forget to […]
Header Tank Water Level Controller Circuit
This Header Tank Water Level Controller Circuit control water level in header tank, it stops motor when tank is full and start motor when tank is empty. Also, it saves water and save electricity and there is no need to watch tank every time, as the circuit works automatic with sensor in tank. Circuit Working: […]
Motor PWM Speed Controller Circuit using IC 555
Do we need to adjust the voltage control knob to change the motor speed? then this smart Motor PWM Speed Controller Circuit using IC 555 to control DC motor speed. Also, it turn motor power ON and OFF very fast so motor gets average voltage and its speed changes; like dimmer switch but for motor. […]
Clap Switch Circuit using IC 4017
The Clap Switch Circuit using IC 4017 turns ON and OFF with a clap sound; it uses a speaker as a microphone because both components have a similar construction; therefore, a speaker can also work as a microphone in this circuit. Circuit Working: Parts List: Components Values Quantity Resistors (All resistors are 1/4 watt) 3.3k […]
PWM Motor Speed Control Circuit using Two Transistors
In this article, resistors can provide basic speed control, but they cannot adjust motor speed efficiently or smoothly. Therefore, this smart PWM Motor Speed Control Circuit using Two Transistors offers a more effective solution. It works like a dimmer switch for the motor and we can turn a knob like a potentiometer to change how […]
