Pulse Width Modulation

Pulse Width Modulation (PWM) is a technique for controlling the average power delivered by an electrical signal. By averaging the output over time, the result is an analog signal that can be used to control devices such as motors, LEDs, and buzzers.

Fading LED

Use PWM to fade an LED.

Servo

Use PWM to control a servo motor.

Buzzer

Use PWM to control a buzzer.

Input

Tutorials on using pins as input.

Button

Use a button.

Binary sensors

Use binary sensors.

Touch sensor

Use one of the ESP32's pins as a touch sensor.

Analog to Digital Converter

Use the built-in analog-to-digital converter (ADC).

Potentiometer

Use a potentiometer with an ADC.

I2C

This section provides an introduction to I2C and guides you through using it with different sensors and devices.
