Interfacing and Basic Arduino Example

To interface a slotted optical switch with your Arduino, you'll typically need to connect the VCC pin to the Arduino's 5V, GND to the Arduino's GND, and the output pin to one of the Arduino's digital input pins2015414—Upload the sketch, then remove the power, connect the shield as shown in the picture above and reconnect the power and the PWR LED will light.
