Hello everyone,


I open this forum because I need to know if I can use some of the digital pins of the arbotix as another serial port, since I need to have two different ways to communicate with two computers, a serial port to move some engines and another port to make a graphical interface among them.


Thank you!!


Urko.

The Arbotix-M has two serial ports:
The first Serial port is typically either the XBee or the FTDI cable (both use same pins).
The Second Serial port is the one that is actually used to drive the servos.

The only option beyond that is to use something like the SoftwareSerial library, to create a serial port. But there are limitations on how well that works.
