Line tracking sensors - Wiring up?

[ahmed]

Can someone provide me with a diagram for wiring up the line tracking sensors or guide me through that?

We had them wired up but the sensors read bogus values.. any help? :]

Brown - +12v
Black - signal pin on a digital input
White - signal pin on a digital input

Note: you only need the Black OR the white hooked up since they are mirror values of each other (0 or 1).

Banner Sensors Note:

There are two types of Banner sensors

Visible (red LED)
P/N ..VN6. = visible = suitable for line tracking ~4"

IR (can't see)
P/N = IR = suitable for proximity sensing ~15"

Black/White each need the RC's built-in +5v 100K pull up in the digital IO port.
(else you see nothing - unterminated open collector)

else to test w/o IO port connection, connect ~5k-100k ohm resistor
from ea. W & B to +5V and use meter or scope to sense the output.

use Black: (+5v) high = off line, (~0v)Low = on line (same logic as IR rcvr)
use White: (+5v) high = on line, (~0v)Low = off line

There are LEDs on the front of the Banner sensors
that visually indicate the sensed state
that the Black/White communicate to the RC digital input.
