ADC or Analog to Digital Converter is device which changes analog signals i.e 0 & 1 into digital signals. The ADC is used to convert an analog voltage (a voltage that vary continuously within a known range) to a 10-bit digital value. For instance, it can be used to log the output of a sensor (temperature, pressure, etc) at regular intervals, or to take some action in function of the measured variable value.
