ir remote

Archiver

I plan to control many lights in my car using a BS2sx. I would like
to use my sony PDA as the remote for the system. Does anyone know of
a schematic that I could use to have the stamp recieve the data from
my PDA.
Thanks in advance!

We're just getting ready to release a new IR receiver/transmitter product.
It is designed to decode popular RC-5 [noparse][[/noparse]a Philips protocol] remote signals.
The kit comes with code and schematics. One of the examples is an RC-5 key
code explorer which will let you get your PDA setup adjusted and tell you the
values of each key code [noparse][[/noparse]RC-5 uses two bytes: one for "system" the other for
"key"].

The connections are easy: One pin from the BASIC Stamp to the device [noparse][[/noparse]it also
needs +5v and ground] is all it takes. You'll use SEROUT to send commands to
the device and SERIN to get information back. It also has a buffer so that
it can receive IR codes while the Stamp is busy doing other things.

Note that IR interference can be problem in outside environments. Our device
is "smart" [noparse][[/noparse]has an onboard micro] and won't decode incorrectly, it may just
reject all signals if there is too much ambient IR. This should be
considered in your application -- you may need to shield the IR receiver from
possible sources of interference for proper performance.
