ESP32 Web Server Real Time ADC with MIT app inventor

Описание: In this tutorial, I 'll Published how to read the analog value using web server and MIT app inventor over WiFi using ESP32 development board. In this project an angular gauge display using canvas method and real time graph using the Chart 2D are applied. The ADC value is printed in local webpage and web string input to android application for display and graph purpose. A pot is connected power 3.3V, ground and analog pin of ESP32 for voltage measurement. Finally the variable voltage from pot 0 to 3300mv is displayed in Webpage and android application.
