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.

+

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. Similarly, GPIO4 and GPIO7 provide PWM to the left- and right- side DC motors to rotate in a counter-clockwise direction. diff --git a/ESP-IDF_Robot/tutorial/docs/build/html/searchindex.js

+ 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. +

+

A pair of PWM channels are required for defining rotation speed and direction of the DC motors on each side. In particular,
