Important Notes:
- The 220 Ω resistor is a pull-up in parallel with the LED. The LED needs to be one with an internal resistance (Standard RED 5mm LED with internal resistance is recommended)
- The board has a normal HIGH and triggered LOW. The LED will be ON when the sensor hasn’t been triggered and will turn OFF when it has.
