class ADC – analog to digital conversion¶
The ADC class provides an interface to analog-to-digital convertors, and represents a single endpoint that can sample a continuous voltage and convert it to a discretised value.
import machine adc = machine.ADC(pin) # create an ADC object acting on a pin val = adc.read_u16() # read a raw analog value in the range 0-65535
Take an analog reading and return an integer in the range 0-65535. The return value represents the raw reading taken by the ADC, scaled such that the minimum value is 0 and the maximum value is 65535.
