How to connect digital sensors to Revolution Pi, the industrial Raspberry Pi 

This video shows you how to use digital inputs with the Revolution Pi.
In this video, we are using an ifm UGT582 ultrasonic sensor.
But it works the same for inductive sensors, push buttons and other inputs that give you just a digital on/off signal. The sensor's pinout is:
- (1 brown) 24V +
- (2 white) Analog output
- (3 blue) 24V -
- (4 black) Digital switching output The black one (4) is the one we use in this video.
