Description

ESP32 Robot Controller

This project was born from a tutorial I worked on where I established communication between a Raspberry Pi and ESP32 using BLE. The link is shown below.

It was then I decided to build a PCB that would allow me to control a Raspberry Pi remotely through BLE which can be used to control a Raspberry Pi robot. This video shows why I decided to build my PCB.

The goal is to simplify the process and not require a breadboard and a bunch of wires to control a Robot. This is great for educational purposes and great for hobbyists.

Medium article detailing my successes with the board posted here. This article details the lessons I learned from the Pico W board as well as some of the basic tests I ran.

Here is the first YouTube video showing it work live for the first time. I show you the buttons and the potentiometer work for the first time.

Here is the video of the ESP32 Controller controlling a Raspberry Pi Robot via BLE or Bluetooth Low Energy.
