Resistors can help in some ways but they are not good for smoothly changing motor speed. That is why a smart PWM Motor Speed Control Circuit using Two Transistors is used. It works like a dimmer switch for the motor. We turn a knob like a potentiometer to change how much power the transistors get. […]

Simple Servo Motor Controller Circuit
Think about a motor which is very special. It can turn to be very exact, this small circuit is like a brain. It tells motor how much to turn using small electric pulses. Long pulse motor move more then the short pulse motor move less. We can say it what to do like move robot […]
AC Drill Speed Controller Circuit
Now one can control its own drill. AC Drill Speed Controller Circuit is like cruise control but for drill. It helps one to change motor speed so one can work better for any job. Very good when one is doing soft work like wood or metal but need careful hand. There is no need for […]
Adjustable DC Motor Speed Controller Circuit
To begin with, Adjustable DC Motor Speed Controller Circuit with Reverse Forward Facility discusses about how to make one simple circuit to control DC motor speed and direction, it uses one popular chip called IC 555 and one special switch. Hence, we can change motor speed by turning one knob which controls power and send […]
