In this tutorial, we are going to make the Home Automation
Hey techies, have you ever imagined that you can control your home appliances remotely? In this tutorial, we are going to make "Home Automation using ESP8266 ESP01 Web Server & Relay Module" to control Home appliances from the Local Networks. Using relays with the ESP8266 ESP01 is the best way to remotely control any AC home appliances. Basically, We will build a web server to see how the relay module works, how to connect the relay to the ESP8266, and control a relay (or as many relays as you want) remotely. So let's get Started!
PCBWay commits to meeting the needs of its customers from different industries in terms of quality, delivery, cost-effectiveness, and any other demanding requests. As one of the most experienced PCB manufacturers in China. They pride themselves to be your best business partners as well as good friends in every aspect of your PCB needs.
