MicroPython – Reading analog signals in ESP8266 and ESP32
The majority of sensors have an analog output. Few sensors come with a built-in controller and can stream the output measurements over a digital protocol. That is why analog to digital conversion is one of the basic features that every microcontroller/port has. The other basic features include digital input/output, analog output, PWM generation, and serial…
