IN1 pin of the L298 IC is connected to pin 8 of the Arduino while IN2 is connected to pin 9. These two digital pins of Arduino control the direction of the motor. The EN A pin of IC is connected to the PWM pin 2 of Arduino. This will control the speed of the motor.
How do you speed up an Arduino motor?
If you push the pedal down, you accelerate to full speed. If you tap the gas pedal, the engine accelerates and then slows down. If you tap it at a constant rate before it slows, you will maintain some of the momentum of the spinning motor and achieve an average (if somewhat jerky) speed.
How do you control the speed of a DC motor using PWM Arduino?
DC Motor control using PWM Signals – Arduino
- Introduction. The DC motor speed in general is directly proportional to the supply voltage, so if reduce the voltage from 9 volts to 4.5 volts then our speed become half of what it originally had. …

What is the speed of DC motor?
DC controls adjust speed by varying the voltage sent to the motor (this differs from AC motor controls which adjust the line frequency to the motor). Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and 1000-5000 rpm for DC fractional hp motors.
How do you slow down a DC motor?
Most DC motors can be slowed down by reducing the supply level of power, Volts, lower volts and resulting less amps, will create less electrical field and will slow motor down. For more gradual speed control there are electronic solutions that are called PWM (Pulse Width Modulation) controllers or Mosfet H bridges.
How does Arduino stop DC motor?
On Arduino, it’s possible to control the motor. As with the LED, you can control the motor to rotate or stop by turning the power supplied to the motor on and off.
