New to ESP32? Start here! The ESP32 is a series of low-cost and low-power System on a Chip (SoC) microcontrollers developed by Espressif that include Wi-Fi and Bluetooth wireless capabilities and dual-core processor. If you’re familiar with the ESP8266, the ESP32 is its successor, loaded with lots of new features.Updated 5 August 2024New to the ESP..

This article shows how to read analog inputs with the ESP32 using Arduino IDE. Analog reading is useful to read values from variable resistors like potentiometers, or analog sensors.Reading analog inputs with the ESP32 is as easy as using the analogRead(GPIO) function, that accepts as argument, the GPIO you want to read.We also have other tutorials..

This is a simple guide about SPI communication protocol with the ESP32 using Arduino IDE. We’ll take a look at the ESP32 SPI pins, how to connect SPI devices, define custom SPI pins, how to use multiple SPI devices, and much more.Table of Contents:Introducing ESP32 SPI Communication ProtocolESP32 SPI PeripheralsESP32 SPI PinsUsing Custom ESP32 SPI ..

The ESP32 has two I2C bus interfaces that can serve as I2C master or slave. In this tutorial we’ll take a look at the I2C communication protocol with the ESP32 using Arduino IDE: how to choose I2C pins, connect multiple I2C devices to the same bus and how to use the two I2C bus interfaces.In this tutorial, we’ll cover the following concepts:Connect..

Learn to generate PWM signals with the ESP32 using Arduino IDE. We’ll explain two different methods: using analogWrite and using the LEDC API. As an example, we’ll build a simple circuit to fade an LED.Updated 11 June 2024Before proceeding with this tutorial you should have the ESP32 add-on installed in your Arduino IDE. Follow the next tutorial to..

This guide shows how to wake up the ESP32 from deep sleep using the touch sensitive pins. The ESP32 will be programmed using Arduino IDE.The ESP32 can be awake from deep sleep using several wake up sources: timer, external wake up and touch wake up. This article shows how to use touch wake up.To learn more about deep sleep and other wake up sources..

his article shows how to use the ESP32 touch pins with Arduino IDE. The ESP32 touch pins can sense variations in anything that holds an electrical charge. They are often used to wake up the ESP32 from deep sleep.To read the value of the ESP32 touch pins, use the touchRead(GPIO) function, that accepts as argument, the GPIO you want to read.Watch the..

Both ESP8266-12E and ESP8266-07 have one ADC pin that is easily accessible. This means that those ESP8266 boards can read analog signals.
