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.
Today we will look at the amazing ESP32-CAM module from A-Thinker. This 10-dollar module features a 2MP camera, microSD card socket, WiFi, and Bluetooth.
Unlike other ESP32 modules this one does not have a USB port, so you’ll need to use an FTDI adapter to get it working.
In this article I’ll show you how to work with the ESP32-CAM and how to resolve common power and antenna issues.
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.
