Radio shack IR
I have a RadioShack (cat # 275-142) IR emitter and detector... And
i've got no idea how to use them with my basic stamp.
Im quite sure that it's a analog detector (like a normal photocell..)
could someone please explain how to detect IR using this
emitter/detector? Is it possible to modulate it so I don't get false
readings from other IR sources nearby?
Any help would be appricated, I'm not to great with basic electronics.
Thanks
Greg

Go to www.parallaxinc.com , click on downloads, and download their
documention on using IR. Complete with code.

this schematic (All pin# are according to BASIC Stamp 2):
I/O Pin>----(IR)
|-|- Ground
Connect a detector like this:
I/O Pin>----(DET)
|-|- Ground
You need an ambiant light filter to filter out ambient rays of IR. You can get
one from Radio Shack (included in RS# 270-215, a project case/membrane keypad
set, it includes a red piece of plastic, that is the filter.). Place the
detector in the case and put the filter over it. Use the following PBASIC code
(for BS2) to detect IR:
input #
if in# = 0 then yes
replace # with the pin number and yes with the label you wish to go to if there
is ir on the detector.
To send IR you would use:
HIGH #
Replace # with I/O pin number. A little more code would allow you to
send/recieve data using Binary and Infrared!
Hope this helps you!

need a filter because (your right) in any sort of light, the IR isn't
even noticably visable.

strengthen the signal:
Sample IR recieving circuit that turns a LED on when IR is revieved:
________________
-3V+ | /
|
|-|-|--|-(DET)
(NPN)
| \
|___________(LED)___~650~______|
The DET is the detector NPN is a NPN transistor. It is oriented as follows:
/---Emitter
BASE
(NPN)
\----Drain
Try this out
