Hello, i have a project due to be submitted in two days, in need of urgent help. So i hav an rf module connected to my aruino duemilanove.. D pins frm d ht12d decoder connect to arduino 0 1 2 3 digital pins. Al d pins work fine except pin 1.. Once d switch has been toggled d pin voltage goes down and stays down until d switch s held. But in pin 1 d voltage goes low once toggled and stays dat way forever.. All other pins including analog pins are in use. Could anybody tell me d problem, and if possible a solution asap..
Thanks in advance 
Pins 0 and 1 are used for Serial I/O. Be sure not to call Serial.begin() if you want to use them for digital I/O. The serial hardware might interfere with your digital I/O so you may need to cut the trace connecting Pin 1 to the FTDI chip.
Oh that makes sense. I have only been using the serial.print function with a test program. Thank you so much.
