**PWM** stands for Pulse Width Modulation. It is a technique used to simulate analog voltage levels using discrete digital signals. It works by rapidly switching a
digital pin between HIGH (on) and LOW (off) states at a fixed frequency (often, at base frequency of 5 kHz). The duty cycle—the percentage of time the signal is HIGH in one
cycle determines the effective voltage delivered to a device.
**PWM** stands for Pulse Width Modulation. It is a technique used to simulate analog voltage levels using discrete digital signals. It works by
rapidly switching a digital GPIO pin between HIGH (on) and LOW (off) states at a fixed frequency (often, at base frequency of 5 kHz).
The duty cycle—the percentage of time the signal is HIGH in one cycle determines the effective voltage delivered to a device.
A higher duty cycle increases the motor speed, and a lower duty cycle decreases the motor speed. This allows for fine-grained speed control
without needing analog voltage regulators.
