Live Switch is an IoT app used to turn ON and OFF devices, display the status of I/O pins, and vary the PWM value on the local network without using an internet connection. It needs ESP8266 or ESP32 modules to communicate and control. It has customized network values (i.e., IP address, Port number, and PWM resolution), labels, and title. The code is mentioned for the ESP8266 node MCU. You can customize the I/O pins of your choice, However, For a PWM channel you have to select the specific PWM pin.
