the input values are in analog. These values can be read by the Arduino from its specific pins and these values can be used for further use. But before understanding the analogRead(), we have to understand what is the analog value?
Notes: -The Arduino code averages 16 samples and the WiFi is running. The VsCode example was modified to sample all channels, WiFi not active, one sample per channel. Comparing the Arduino esp32-hal-adc.c code with the esp-idf single-read example shows that the calibration functionality for...
