Arduino Serial Begin: Why change from 9600Baud When you use an Arduino these limitations do not apply and you can actually get away with far higher Baud rates because there is no long cable between the PC and the Arduino. 9600Baud is just the accepted default rate used in most example pro...

When using two software serial ports, you have to switch ports by listen()ing on each one in turn. Pick a logical time to switch ports, like the end of an expected transmission, or when the buffer is empty. This example switches ports when there is nothing ...
