Schematic
When the PIR module detects motion, IO14 will go high, and the LED will be lit. Otherwise, when no motion is
detected, IO14 will be low, and the LED will turn off.
Note: The PIR module has two potentiometers: one adjusts sensitivity, the other adjusts detection distance. To make
the PIR module work better, you need to turn both of them counterclockwise to the end.
