Either arduino uno or any digital controller to implement PID loop and for control the speed of motor and sending or receiving data by serial communication Bluetooth. But,three DC motor controls might be enough for most of the small projects. This circuit, where a DC motor is controlled using an Arduino UNO, can be used in applications like Arduino based robots, speed as well as direction control of DC … One of the easiest and inexpensive way to control DC motors is to interface L293D Motor Driver IC with Arduino. Before we learn how to control a DC motor with the Arduino, we need to understand some basic concepts of motor control. Power = 300 watt . If you use a motor with high current and voltage rating you will have to modify the motor driving circuitry a little bit. Basic Arduino Code to control the motor to Start, Stop and control the speed of your motor using Pulse Width Modulation (PWM) Parts List and Tools. By controlling the motor, we mean controlling its speed and direction of rotation. It can control both speed and spinning direction of two DC motors. In this lesson, you will learn how to control a small DC motor using an Arduino and a transistor. Encoders will be used to provide feedback on motor speed and the individual components were tested in the last post: Simple Arduino DC Motor Control with Encoder, Part 1. DC output = 24 volt - 10A.

This feature is enabled in UNO to get variable voltage over constant voltage. When you want to drive DC motor with Arduino, you needs some sort of motor driver module which can run motors and control the direction and speed of the motors. Arduino PWM Motor Control – Video Arduino DC Motor Control. Motor speed control using arduino. This term stands for those methodologies of control in which they control both torque and speed together. Whenever the button will be pressed on the android app, the Arduino will receive the data through the serial communication and will compare this data with the already saved in the data. If this is your first time using Arduino we suggest learning the basics from one of the many great beginner tutorials available through Google and YouTube searches. Arduino (I've used an Arduino Micro but any Arduino will suffice) 12V (or equivalent >5V) DC Motor This will control the speed of the motor. Arduino PWM Motor Control. This project can control only three DC motors that’s because of limited PWM pins available in Arduino boards.
