| Multiple Serial test | |
| Receives from the main serial port, sends to the others. | |
| Receives from serial port 1, sends to the main serial (Serial 0). | |
| This example works only with boards with more than one serial like Arduino Mega, Due, Zero etc. | |
| The circuit: | |
| - any serial device attached to Serial port 1 | |
| - Serial Monitor open on Serial port 0 | |
