Can you control a DC motor with a potentiometer?
Yes, you can use a potentiometer to control motor speed. When used to vary voltage, a potentiometer can be connected to a motor and vary the voltage (and therefore power) delivered to a motor which will control its speed.
How does Arduino control speed of DC motor with potentiometer?
Arduino DC Motor Speed Control Potentiometer
- Step 1: Part List. 1) Arduino.

Can I control the speed of a DC motor with Arduino?
You can not regulate the speed of a DC motor directly but using this circuit it is possible to do so. We are using an L298N motor driver module here but you can use other drivers as well. The image of the complete project is also given below.
Can you power a DC motor with Arduino?
To power the motor, you need to send 5V through it and then on to ground. This voltage spins the motor, but you have control of it. To give your Arduino control of the motor’s power, and therefore its rotation, you place a transistor just after the motor.
How do you control the RPM of a DC motor?
Thus, the speed of a DC motor can control in three ways: By varying the flux, and by varying the current through field winding. By varying the armature voltage, and the armature resistance.
How does a potentiometer reduce voltage?
How to Use Potentiometers to Adjust Current and Voltage
- Attach the other end if the limiting resistor to one of the fixed terminals of the potentiometer.
- Conjoin the negative probe of the current meter to the negative terminal of the power supply.
- Rotate the shaft to vary the potentiometer resistance.
How do I choose a potentiometer?
Choosing the right potentiometer is easy if you know what to look for. Pick the right package and size for your potentiometer. Examples include a rotary, a dial, or slide switch. The package and size are necessary to make sure the potentiometer fits in your circuit and that you can reach it to adjust it.
