Hello,

I have little trouble about the possibility to use Analog IN Pins (A0 to A5) on Arduino UNO as RX/TX.

Your support is requested.

Thank you for all.

What have you tried sofar?

Tip: you can refer to the analog pins as pin 14-19 .

Hi,

All Digital Pins are already used and i still need one Serial port. But i have only the Analog IN available.

So my question is :

1/ Can i use Analog IN as Serial port?
2/ How ?

Thx.

No. But the analog pins are also digital pins. They are aliased using A0, A1, etc. Just use An where you would use n in the SoftwareSerial constructor call.
