whats the idea of doing so?Huh
its just a pointless idea
oh, and use a resitor >1k, or let the led be commanded via a transistor. This way, you won't introduce additional capacitance over the wires so you can use high baud rates.
I've got the LEDs hooked up and they're doing a decent job. Obviously, not as informative as an oscilloscope, but the intensity / frequency of the light blinking already helped me debug the fact that my microcontroller and my bluetooth module were speaking at different speeds. It's nice to just have a status indicator always around.
For this job you obviously need a transistor...Cause if the Led draws current you won't get any data though...
TrickyNeckro,I've never directly used a transistor in a circuit design before, but I have a rough idea of how they work. Would you be willing to post a schematic?
