# Quick Answer: How do you reverse the direction of a DC motor in Arduino?

Contents

To control the direction of the motor, the pins in1 and in2 must be set to opposite values. If in1 is HIGH and in2 is LOW, the motor will spin one way, if on the other hand in1 is LOW and in2 HIGH then the motor will spin in the opposite direction.

## Can you reverse the direction of a DC motor?

DC motors, like AC motors, can be configured to turn in either direction. Their direction can be easily controlled by inverting the polarity of the applied armature voltage by reversing the armature leads.

## How does a DC motor run forward and reverse Arduino?

Run DC Motor Reverse and Forward Using L293d Arduino

3. Step 3: Code. Void setup () { pinMode(13, OUTPUT); PinMode(12,OUTPUT); } Void loop(){ digitalWrite(13, HIGH);

## How do you rotate a DC motor in both directions using Arduino?

Connect the terminals of the DC motor with the output pins (OUT1 and OUT2) of L298 motor controller. Connect L298 motor controller’s pin IN1 and IN2 with the Arduino UNO’s pin 2 and 5 respectively. Now, connect ENA pin of L298 motor controller to the Arduino’s pin 9. Connect the power supply to turn on the circuit.

## How do you control the speed and direction of a DC motor?

In summary:

1. To control the direction the DC motor is spinning you use the input 1 and input 2 pins;
2. Apply LOW to input 1 and HIGH to input 2 to spin the motor forward. Apply power the other way around to make it spin backwards;
3. To control the speed of the DC motor, you use a PWM signal on the enable pin.

## How do you change the direction of a DC motor?

So in order to change the direction of rotation, we can simply reverse the voltage, causing the current to flow in the opposite direction, changing the force by 180 degrees and the motor to be driven ‘backwards’.

## How do you reverse and forward a DC motor?

When the switch lever is in the top position, the motor rotates forward. If your motor rotates in the opposite direction than you expected or wanted, simply reorient the switch in your hand so that lever is facing the bottom, and then toggle the lever to the top.

## What is DC motor Arduino?

A DC motor (Direct Current motor) is the most common type of motor. … If you switch the leads, the motor will rotate in the opposite direction. Warning − Do not drive the motor directly from Arduino board pins. This may damage the board. Use a driver Circuit or an IC.

## How does l293d control motor speed?

The L293D quadruple half-H drivers chip allows us to drive 2 motors in both directions, with two PWM outputs from the Arduino we can easily control the speed as well as the direction of rotation of one DC motor.

## How does an engine rotate clockwise and anticlockwise?

A DC motor can be very simply rotated both ways in clockwise as well as in anticlockwise directions by flipping the supply inputs to it. However the above reversing requires flipping of both of its wire polarity with the connected supply. Therefore it cannot be done by using a single relay or switch.

## How do you change the speed of an Arduino DC motor?

You can only control the speed of a DC motor with PWM if the motor has a significant mechanical load. A unloaded motor will just keep running unaffected during the off parts of the PWM cycle. Attach a pot to control the PWM value and pinch the motor spindle between your fingers. Then you will feel the speed change.

## How do you control the speed of a DC motor using PWM Arduino?

So depending on the size of the motor, we can simply connect an Arduino PWM output to the base of transistor or the gate of a MOSFET and control the speed of the motor by controlling the PWM output. The low power Arduino PWM signal switches on and off the gate at the MOSFET through which the high power motor is driven.

## How do you speed up a DC motor?

Thus, the speed of a DC motor can be controlled in three ways:

1. By varying the supply voltage.
2. By varying the flux, and by varying the current through the field winding.
3. By varying the armature voltage, and by varying the armature resistance.

## How can you reduce the speed of a DC motor?

If you want to reduce rpm without compromising speed regulation then use a voltage regulator or PWM controller to lower the motor voltage. If you also want higher torque then use a gearbox (which increases torque by the same proportion as it reduces shaft rpm).

## Which of the following is used to determine the direction of rotation of DC motor?

Which of the following rule is used to determine the direction of rotation of D.C motor? Answer 4. Fleming’s left-hand rule.
