7 “Let's use the A/D converter.”
This section describes the processing to convert the analog signals input to the microcomputer into
the digital signals by using the A/D converter and to load the digital signals into the
microcomputer.
This Starter Kit can control the value of the voltage applied to the analog pin for the A/D converter
by using the volume tab mounted on the board.
microcomputer by using this tab. The input analog signal can be converted into the digital signal
by the A/D converter and processed by the microcomputer.
7.1
Do you know the difference between analog and digital? Those are explained as follows in a
dictionary.
Although you read the above definitions, you may have a hard time picturing them.
Intuitively speaking, initially, everything is in analog value. At the moment a person tries to
determine the size or variety of the analog value, the quantity becomes digital value. In other
words, a digital value exists only when an analog value exists. A digital value is what an
analog value is divided into some levels for easier handling and converted to easier
