However most PICmicro devices also have a facility to take in a voltage from 0 V to the supply voltage and to measure that voltage. This process is carried out inside the PICmicro device by the Analogue to Digital Converter (ADC) module of the PICmicro device. In this section you will learn about the ADC functions of the PICmicro and how to control the ADC using Flowcode. In this section we will make a complete system for controlling a small Hi-Fi. This will introduce several new components. Specifically in this section you will learn: * How to use the Port B change interrupt * How to use the ADC * How to break down project development into sections (:nl:)(:table style="clear:both":)
