.. admonition:: What is PWM?
PWM (Pulse Width Modulation) is a technique used to simulate analog voltage levels using digital signals. It works by rapidly switching a
digital pin between HIGH (on) and LOW (off) states at a fixed frequency. The duty cycle—the percentage of time the signal is HIGH in one
cycle—determines the effective voltage delivered to a device.
**PWM** (Pulse Width Modulation) is a technique used to simulate analog voltage levels using ddiscrete igital 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.
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.
A pair of PWM channels are required for defining rotation speed and direction of the DC motors on each side.
In particular, **GPIO6** and **GPIO5** provide PWM to the left- and right- side DC motors to rotate in a **clockwise** direction.
