However, if the motor power supply voltage exceeds 12V, the jumper must be removed to prevent damage to the on-board 5V regulator. Important: If the motor power supply voltage is less than 12V, the jumper can be left in place. Conversely, a lower duty cycle decreases the average voltage, reducing the motor speed. A higher duty cycle results in a higher average voltage, increasing the motor speed. It involves sending a series of ON-OFF pulses, where the average voltage is adjusted by changing the width of the pulses, known as the Duty Cycle. PWM is a commonly used technique for this purpose. The speed of a DC motor can be controlled by manipulating its input voltage. PWM (Pulse Width Modulation) – Controlling Speed This can be achieved by combining two techniques: PWM and H-Bridge. To have precise control over a DC motor, we need to be able to adjust its speed and spinning direction.
