Analog to digital conversion are required in embedded systems because most of their surroundings comprise of analog signals and the embedded processors can process only digital data. This tutorial shows how to use the internal ADC module of a PIC microcontroller to read an external analog signal and convert it to a digital number. The conversion output will be displayed in a character LCD.
