Hello friends, I hope you all are doing great. Today, I am going to share the ESP-01S Library for Proteus . It brings the ESP-01S to Proteus: the tiny black ESP8266 Wi-Fi module with eight pins that gives any Arduino Wi-Fi through AT commands . Your sketch sends AT+CWJAP , AT+CIPSERVER or AT+CIPSTART over a serial port, and the module joins a router, serves web pages and talks TCP and UDP with other boards, right inside the simulation. And it has the one thing that makes the ESP-01S different from its older brother: the blue LED on GPIO2 , which your sketch can switch with AT commands.
