Simple Servo Motor Controller Circuit using Arduino
Servo motor is small machine part. It can turn to exact position. People use it in many things like robots, CNC machines and factory machines. This post for Simple Servo Motor Controller Circuit using Arduino show how to control servo motor using Arduino. It also use push buttons, capacitors, resistors and IC 7809 for power. […]
DC Motor Speed Controller Circuit using Arduino
This project for DC Motor Speed Controller Circuit shows how to control DC motor speed using Arduino, MOSFET and potentiometer. Arduino make PWM signal to control MOSFET gate. MOSFET work like switch and control voltage to motor and changes speed. Arduino speed controller is simple and with low cost. It can control motor, light and […]
Simple Solenoid Driver Circuit
A Simple Solenoid Driver Circuit is a setup to control solenoid using low voltage signal. Solenoids are like magnets and they change electric power into movement. They need more voltage than small digital parts like microcontrollers can give. The driver works like a switch and it lets small signal turn big current ON and OFF […]
H-Bridge PWM Driver Circuit using IC 555
H-Bridge PWM Driver Circuit using IC 555 controls DC motor speed and direction. In this circuit no driver transistors are used. Motor connect direct to two IC 555. Motor speed and direction can change. We can only use two IC 555 to control the motor. This circuit is easy to make and is used for […]
