    Arduino core for the ESP32

    How do you have the adc wired to the esp? Your call to SPI.begin() with no parameters means the library will use default gpio numbers. The defaults vary by board type. See https://github.com/espressif/arduino-esp32/blob/master/libraries/SPI/src/SPI.cpp lines 53-67
