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 […]
Simple Capacitive Touch Switch Circuit using IC TTP223
No button needed as this circuit uses a smart chip known as TTP223 to feel our touch. Like magic it touches the pad and it turns ON or OF; as this Simple Capacitive Touch Switch Circuit using IC TTP223 is an easy way to make a touch switch for fun or projects. Circuit Working: Parts […]
Automatic Soap Dispenser Circuit
Automatic Soap Dispenser Circuit is like robot for soap, inside it have a special plan like electric circuit with small parts; also, it has got sensor like small eyes, brain chip like microcontroller, and pump like tiny muscle. Hence, when sensor sees our hand its brain tell pump Give soap! and it gives the right […]
