![]() In this tutorial I will work on DC Motor Direction Control using NI LabVIEW. You can use it in automation projects, for controlling static as well as mobile robots, in transport system, in pumps,fans,bowers and for industrial use as well. You should also have a look at Difference between DC & AC Motors to get a better idea about these motors.ĭC motor has a lot of applications. If you change the polarity then motor will rotate in opposite direction. If we connect these terminals with the voltage supply the motor will rotate. So, a direct current motor is commonly used motor having two input terminals, one is positive and the other one is negative. The word DC is basically an abbreviation of Direct current. You should go through these tutorials they will be helpful in better understanding of the tutorial DC Motor Direction control using NI LabVIEW. #Servo motor arduino labview how to#Today, I am going to share my knowledge with all of you about how to make a simple program for DC Motor Direction Control in LabVIEW. In my previous tutorials, I have also worked on DC Motor Direction Control using Arduino. Before uploading the code, make sure to select Arduino UNO from Tools > Board.Hello friends! I hope you all will be absolutely fine and having fun. #Servo motor arduino labview code#To see the demonstration of the above code, upload the code to Arduino. This will position the servo arm according to the values held in the angle variable that will first vary from 0-180 degrees and then 180 to 0 degrees by using a for loop. Here we are passing the ‘angle’ variable as a parameter inside this function. Inside the loop() function, we will move the servo motor’s arm clockwise and anti-clockwise using the write() method on the servo object. Notice this is the Arduino pin that is connected with the PWM pin of the servo motor. Inside the setup() function, we will attach digital pin10 with the servo object. ![]() int angle = 0 // variable to store the servo position The ‘angle’ variable holds the current position of the servo motor’s arm. Then we will create an object of this library called ‘myloop.’ This will be used to control the servo motor. Myloop.write(angle) // move servo in opposite directionĭelay(20) // waits 20ms between servo commandsįirstly we will include the built-in Servo.h library. Myloop.attach(10) // attached the servo on pin 10 to the servo objectįor (angle = 0 angle = 1 angle -= 1) // goes from 180 degrees to 0 degrees Int angle = 0 // variable to store the servo position Servo myloop // create servo object to control a servo ![]() The following code is written for calculated angle position control of servo motor using Arduino UNO with the Servo.h library. This basic sketch will show us how to control a servo motor’s position with specific or calculated angle. Copy the code given below in that file and save it. Open your Arduino IDE and go to File > New. Servo Motor interfacing with Arduino UNO Arduino Sketch Controlling Servo Motor The width of the pulse has a direct relation with the angular position of the motor. That means the control signal pulse should be applied to the PWM pin every 20ms duration. The frequency of the PWM signal should be 50Hz. To control rotation, we apply pulses to the PWM pin of the servo motor. The position of the servo rotator is directly related with the width pulse applied to the PWM signal of the motor. ![]() How to control Servo motor rotator movement? You just have to call a function used in servo.h library and its as simple as that. So you don’t need to write lengthy code for servo motor. Fortunately Arduino IDE already has a built-in library (servo.h ) for servo motor control. We can calculate the servo motor’s position by varying the duration of pulses to servo with the help of Arduino Uno R3. A pulse of duration 1 millisecond causes the servo motor to move one end and duration of 2 millisecond causes the motor to move other end. Servo Motor WorkingĪ servo motor responds to changes in duration of pulses. However, the main disadvantage of servo motor is its lower speed and low power limitation as compared to other motors. So the main advantage of servo motor is that it doesn’t require any interfacing circuit. H bridge is used to rotate motor either in clock wise or anti clock wise direction. Servo motor can not move with continuous motion unless feedback potentiometer is connected.
