Project 3 - Introduction
8-Bit Analog Input Project
Signal voltages are not always digital such as zero volts or five volts. Many times they are analog, in that they can vary in voltage level, and that is where an analog-to-digital converter is used to convert the input signal from an analog voltage level to a digital value that the microcontroller can process. This project monitors a potentiometer controlled voltage that lights up an LED when the threshold is crossed.
