ESP32 Tutorial

Build an ESP32-CAM Developers Module

ESP32-CAM Developers Module Project

Simplify your ESP32-CAM experiments by building this simple developers module.

This handy accessory has a solderless breadboard, prototyping accessories, and a built-in power supply that can also be used for other projects and can run on batteries or AC.

It’s an easy build and you probably already have most of the parts.

Using Servo Motors with ESP32

Servo Motors & ESP32

Today we will look at a few different ways to drive a servo motor with an ESP32 microcontroller.

We’ll be using a replacement for the Arduino Servo Library and recompiling classic Arduino servo sketches to work with the ESP32.

We will also drive multiple servos with a PCA9685 PWM module and build a web-based servo motor control.

Getting started with ESP32

ESP32 Introduction

Time to move up to another microcontroller, the ESP32. This amazing device has multiple I/O ports, WiFi, Bluetooth and BLE, analog inputs and outputs and many, many more features!

Today we will get started with the ESP32 by setting up the Arduino IDE as our programming environment and going through some of the example sketches.
