This method is used to control the direction of the DC motor. Of course, not by changing manually but by programming.If we provide power to DC motors below 12V, the motor still rotates but not at maximum speed. It means if we change the voltage of the power supply, we can change the...

Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3 Product ID: 1438 The original Adafruit Motorshield kit is one of our most beloved, so we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors....
You’ll also notice I add a potentiometer and a push button switch. The potentiometer will control the stepper motor speed while the push button will reverse its direction. I’m showing a 24-volt power supply in the diagram as it is what I used for my motor tests. You should use a su...
divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed. ...
The speed of the stepper motor is determined by the frequency of the pulses we send to the STEP pin. The higher the frequency, the faster the motor runs. You can control the frequency of the pulses by changingdelayMicroseconds()in the code. The shorter the delay, the higher the frequency...
Since we are using the Arduino stepper library, we can set the speed of the motor using the below line. The speed can range between 0 to 200 for 28-BYJ48 stepper motors. stepper.setSpeed(200); Now, to make the motor move one step clockwise we can use the following line. stepper.ste...
(pwm,255);/* setting pwm of the motor to 255 we can change the speed of rotation by changing pwm input but we are only using arduino so we are using highest value to driver the motor *///Clockwise for 3 secsdelay(3000);//For brakedigitalWrite(in_1,HIGH);digitalWrite(in_2,HIGH);...
Let’s resolve that and build a robot car with speed sensors. Along the way we’ll learn how to use Interrupts, a valuable programming technique. Read More » Using the HC-SR04 Ultrasonic Distance Sensor with Arduino The HC-SR04 Ultrasonic Distance Sensor is a staple in robotics projects....
