I have figured out code to move the DC Motors in one direction (forward) using a switch but I cannot find sample Arduino code that will reverse the direction of the DC motor so the car can move backwards. So, for DC Motor Direction Control, I have used Arduino UNO baord, so you should also download this Arduino Library for Proteus so that you can use Arduino boards in Proteus software. 5. In this project, an Arduino based speed and direction control of DC motor without using Motor Driver IC is designed. 5 sec at 80% speed continuously. Find yourself a DC motor that runs on low DC voltage within the range of 5 – 15V. The third thing to do is to teach Arduino to reverse the polarity to the motor when throttle is in the "reverse" position. Recommended Readings: When current is passed through, it spins continuously in one direction until the current stops. I have button bit, slide dimmer, and variable switch. To control the direction the DC motor is spinning you use the input 1 and input 2 pins; Apply LOW to input 1 and HIGH to input 2 to spin the motor forward. Give Pin 1 (Enable 1) PWM input to control the speed. So, if the button is pressed, this will be False, otherwise it will be True. By connecting an L298 bridge IC to an Arduino, you can control a DC motor. Rather than having to unplug the motor to reverse it, this clever chip allows us to reverse the polarity to the motor using logic level signals from a microcontroller. If the button is pressed, the motor will run in forward, otherwise it will run in reverse. Find a motor. Since the average value obtained with the for loop is sent to the motor, we get rid of these tiny jumps. Running a DC(direct current) motor in both clock and anti clock wise direction using a microcontroller is very easy. When the DC motor is in high speed, it will glow the LED. 4.when reed switch attracted by the magnet remains the stop and start to forward direction. The project is designed to develop a four-quadrant speed-control system for a DC motor. The switch S1 is used to instantly reverse the motor direction whenever required. +Motor Power IN recieve the motor power supply (5,6, 7V and sometimes 24V or more) Motor 1 and Motor 2 are connected to the motor’s wires. A DC Motor can’t be connected to a Microcontroller as the output current of the Microcontroller is very small and it cannot drive the motor. This, in turn, means that mostly they should run with similar performance in both forward and reverse directions. start or stop the motor as well as provides DC BREAK for instant STOP One has to select arduino pins for the motor then start rotating motor using given library functions The Workpiece starts moving on the left side and moves to the right when the start button is pressed. Arduino IR Remote Library. When it reaches the rightmost limit, the drive motor reverses and brings the workpiece back to the leftmost position again and the process repeats. +Motor Power IN recieve the motor power supply (5,6, 7V and sometimes 24V or more) Motor 1 and Motor 2 are connected to the motor’s wires. You can easily interface it to an Arduino or any other microcontroller. In the next line, send output to the pin we will use for the DC motor by using analogWrite(): analogWrite(MOTORPIN,speed); This will send the value of speed to MOTORPIN as an output. The DC motor in your Arduino kit is the most basic of electric motors and is used in all types of hobby electronics. Wiring of DC Motor. I have also provide the simulation and the code for DC Motor Direction Control but I would recommend you to design it on your own so that you learn from it. Field terminal consist of F1 and F2. Connect a switch to digital input 2 on the Arduino. Unless specifically marked with a + or -, DC motors have no polarity, meaning that you can swap the two wires over to reverse the direction of the motor. Normally, in forward direction the DC supply will be given such as F1 – Positive and F2 – Negative, to change the direction the polarity should be F1- Negative and F2 – Positive. Connect second DC motor to Pin 11 and Pin 14 of L293D. DC Motor Direction Control using Arduino.
