Re: Line tracking sensors - Wiring up?
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.
