Topic: connecting an IR receiver to the serial port
Hi,
I would like to be able to use an IR remote controller to control my Chumby guts kit (Chumby classic based).
As I'm building the Chumby into a wall I won't have room for any USB peripherals so I will need to use the serial port.
As the serial port appears to be running at 3V (right?) and my IR chip is able to run at 3V too, should I be able
to simply hook them up as in the drawing below?
------------ --- Vcc ----- 100Ohm --- + -------+---------------- Chumby +3V
| | | |
| | 100nF 10K Ohm
| | | |
| IRM38BL | --- data ----------------------------+------------------ Chumby RX
| | |
------------ --- GND ------------------+--------------------------- Chumby GND
My electronics skills are a bit rusty so I'd like to know up front whether this should work before I toast my Chumby :-)
