Receives from the hardware serial, sends to software serial.

Receives from software serial, sends to hardware serial.

|
|
The circuit:
|
|
* RX is digital pin 2 (connect to TX of other device)
|
|
* TX is digital pin 6 (connect to RX of other device)
|
|
|
|
Note:
|
|
Not all pins on the Elbear Ace-Uno support interrupts,
|
|
so only the following can be used for RX:
|
|
2, 3, 4, 5, 8, 9
