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. […]

Solar Motor Robot Circuit
This Solar Motor Robot Circuit run by sun with no battery needed, as it uses special circuit called “solar engine” which works good with small solar panel. Also, robot can move even when sky is cloudy. Circuit Working: Parts List: Components Values Quantity Resistors (All resistors are 1/4 watt unless specified) 100k 1 1M 1 […]
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 […]
Solar Tracker Circuit
Think like small helper robot for our solar panels. Solar Tracker Circuit works like smart assistant which helps solar panels to always look at sun, as sun moving in sky the whole day. Also, this circuit have sensor it sees where sun goes and change panel direction by itself. When panel always faces the sun […]
Simple IC 555 PWM Generator Circuit
Imagine our devices as a little translator! This Simple IC 555 PWM Generator Circuit work like that translator but for signal and electricity, as it uses one special chip called as IC 555 to take message and make it like pulse signal. Also, this pulse signal can help control things like light brightness or motor […]
Simple Servo Motor Controller Circuit
Think about a motor which is very special, which can turn to be very exact. Here, this small circuit is like a brain which tells motor how much to turn using small electric pulses. Long pulse motor move more then the short pulse motor move less and we can say it what to do like […]
