esp_get_adc() reads the analog-to-digital converter channel (1-8) specified.
The analog input range of each ADC channel is software-configurable for ranges of ±/
10V, 0 through +10, -10 through 0, ±/5V, ±/2.5V, and ±/1.25V.
ADC channels are located on the analog I/O connector on the controller card.
