Simple Relay Control with ESP32, Smartphone, and Netconn (Explained) | #IoT #IoTuesday

Installment #14 from lucadentella’s ESP32 tutorial repository on GitHub shows how to control a relay from a web page interacted with via a smartphone touchscreen. Luca does a brilliant job on his blog of explaining netconn and the breakdown of how the webserver operates on the ESP32.

One of the most popular projects among the ones included in my tutorial about the enc28j60 chip is fore sure WebRelay. This project allows to control an output pin of Arduino using a simple web page, designed to be accessed also using your smartphone. Today I’m going to show you how to implement a similar project with the esp32 chip; it’s also the opportunity to teach how to write a TCP server, especially a web server.
