Let's create a program to display the potential based on the contents so far. Input the
adjusted voltage, convert the analog signal to digital, and obtain the digital value. Also, light
the LED to display the potential.

How to create and execute a program to display potental
Figure 7-3 Variable resistor shows the symbol of a variable resistor. The volume is
the variable resistor that you use in an experiment in a science class. This Starter Kit
uses the circuit configuration shown in
Figure 7-4 Peripheral circuitry of voltage adjustment . By using this tab, the
voltage is changed and applied to the target pin of the A/D conversion. The applied
voltage is digitized into 1024 levels so that it can be used as an internal signal.
Let us now create the actual program. The contents of the program are to use the A/D
converter to digitalize the potential of the applied voltage and to determine the number
of LEDs to be lighted according to the potential. The main operation of the program is
described below. The flow of the program is shown in Figure 7-5 Flow of the
program .
