Hall Effect Sensor

This sensor detects when a magnet comes near, and uses this to sense things. The LED is always on, and will turn off when the magnet is closed, essentially breaking the circuit. Used as a sort of limit switch sometimes.

Wiring

Note

The only cable you need is a PWM

1. Connect the PWM power, ground and signal wires onto the RoboRIO

2. Black is ground, red is 5 volts and the white wire is a signal wire
