Line Sensor

[Robototes2412]

Its a digital input, hook up the brown to the negative and the blue to the positive, the black is normally closed and the white is normally open. Hack a pwm cable so that the black and white line up (read: soldering iron).

We got all of them, but we don't get why it shows all of the 3 sign (Green, Yellow, Yellow and Orange)....

I hope nobody follows this advice. It's completely wrong.

Brown is the positive supply to the sensor, and needs to come from the red terminal of a 20 Amp circuit on the Power Distribution board (or from an output on the solenoid breakout if you want to use 24 volts instead). Blue is the power return (ground), and should come from the adjacent black terminal on the Power Distribution board.

Either black or white can be connected to the SIGnal pin of a Digital Input on the Digital Sidecar. The LabVIEW autonomous line-following sample code expects the white wire.

Blue is negative and Brown is positive, that's what a site on the internet was saying....

We've been using Blue as negative and brown as positive and nothing has broken by us doing it.

Which is exactly the setup Alan described and is the opposite of what you originally posted.

I agree.

Robototes2412, please remove/correct your post.

So in this setup, what is done with the black wires? Just connect them (a) to nothing or (b) to each other?

Neuter them. (Cut them off).

That's what I thought. The kids managed to tear out several wires yesterday, and I wanted to be sure how to re-wire them properly (and am limited on time before build).

I won't GIVE them the answer, but I wanted to be sure what the answer IS so that I can check their work and make 'suggestions'...
