Re: Why does the gyro need the ADC?
Because, the gyro returns a signal ANYWHERE between 0v to 5v (e.g. 2.2v). So using an ADC would allow you to translate that particular voltage at a certain point in time into a numerical value (e.g. 0 to 255 for 8 bit) so that your program can translate that into a human related reading (like 0 to 300 degrees)
