esp_set_adc_range() will set the range of all eight (8) ADC channels whereas
esp_get_adc_range() will retrieve the current setting.
The analog input range of each ADC channel is software-configurable for ranges of ±/
10V, ±/5V, ±/2.5V, and ±/1.25V.
ADC channels are located on the analog I/O connector on the controller card.
