I have an LED project I'm working on, and I want to incorporate Bluetooth so that it can be controlled via smartphone.
I got an HC-06 and Arduino Nano for this purpose, but now I am not sure it will work based on some things I read online: http://forum.arduino.cc/index.php?topic=410046.0
The problem is that I want this to be an embedded / self-contained device, so I won't be able to unplug the TX and RX pins every time I want to make changes to the software.
I also have an Arduino Mega, which I don't think has this problem (can anyone confirm?). I would prefer to use the Nano since it is smaller and cheaper, but if the Mega will work then I might just use that.
Any suggestions for how I should proceed?
