About this Calculator:
This PWM Duty Cycle Calculator helps you determine the PWM duty cycle required to achieve a specific motor speed or power level based on various inputs such as desired motor speed, maximum motor speed, and PWM frequency. By providing these inputs, you can calculate the necessary parameters to control motor speed using Arduino's analogWrite() function. See also Arduino Fast PWM vs Phase Correct PWM mode.
Equations Used:
Duty Cycle (%): \( D = \left( \frac{\text{Desired Speed}}{\text{Maximum Speed}} \right) \cdot 100 \)
analogWrite Value (0-255): \( A = \left( \frac{D}{100} \right) \cdot 255 \)
