The schematic diagram:
In this experiment, by programming the Raspberry Pi, we change a value by reading the
status of the Rotary Encoder. When we turn the knob of the Rotary Encoder clockwise,
the value on the terminal will increase; when we turn the knob counterclockwise, the
value will decrease. When we press down the switch, the value will be zeroed out.
