Simple Servo Motor Controller Circuit using Arduino
Servo motors are flexible parts used in many different applications since they are electromechanical actuators that have the ability to rotate to a certain position. Applications for servomotors include automated manufacturing, robotics, and CNC equipment, etc. This post will examine how to use an Arduino microcontroller to drive a servo motor while adding push buttons, […]
DC Motor Speed Controller Circuit using Arduino
This project shows how to regulate the speed of a DC motor with an Arduino microcontroller, a MOSFET transistor, and a potentiometer. The Arduino creates a Pulse Width Modulation PWM signal that controls the MOSFETs gate. The MOSFET acts as a switch, regulating the voltage provided to the motor and so managing its speed. The […]
Simple Solenoid Driver Circuit
A circuit that lets you operate a solenoid with a lower voltage signal is known as a simple solenoid driver circuit. In essence, solaroids are electromagnets that transform electrical energy into mechanical motion. Generally speaking they need a greater voltage than microcontrollers or other digital circuits can readily handle. The driver circuit functions as a […]
Simple H-Bridge PWM Driver Circuit using IC 555
A Simple H-bridge PWM driver circuit that makes use of a IC 555 integrated circuit is used to regulate the direction and speed of a DC motor. In this circuit the important part is driver transistors are not used, instead the load which is a motor is driven directly through the two IC 555s. Circuit […]
Simple Motor PWM Speed Controller Circuit using IC 555
Forget fiddling with voltage knobs, this clever circuit uses a 555 chip and a technique called PWM Pulse Width Modulation to control your DC motors speed. By rapidly switching the motors power on and off in short bursts we can effectively adjust the average voltage, it experiences ultimately controlling its speed. It is like a […]
