Need multiple rxtx connections

Hey guys,

I just started working with the arduino a couple weeks ago and I LOVE it!! Currently, I'm trying to make a bluetooth LCD box. I've got the arduino pro mini to work with both the bluetooth and the LCD but I don't know how to get it to work with both at the same time because they require the RXTX pins... I was thinking about getting a mux/demux but one problem i forsee is that there will be connection issues when I switch the RXTX from one to the other (esp with the bluetooth). Another option was to make some kind of bluetooth sheild but I'm not really sure how to go about this. Can anyone help me with this? Or give any suggestions?


There are limited hardware serial ports (the tx/rx pins), but NewSoftSerial (a google term) allows you to use any pair of pins for serial input/output.

Lots on using serial comms at...

thanks guys!
