ESP32 WiFi Web Server – Control Relay Locally Without Internet

Ever wanted to control a relay (or maybe a servo), attached to one of our projects on the other side of the room. Or the other end of the house, but wanted to keep it all simple and low cost. Even worse, your internet connection drops out just when you want to stop the Robot from chasing the cat!

Well, this book might just help…

ESP32 Control Relay using Windows10 Nodejs and JohnnyFivejs

For this project we are going to flash a custom version of Firmata… first, we will create it with Firmata Builder, set some Wi-Fi and debug variables to our ESP8266, and connect up a Relay. Then we will Install Node.js, Johnny Five js and some other libraries on Windows 10, write a controlling script and run it from the Windows command line to turn the Relay On or Off.
