I have device set up like a combination of Raspberry Pi, Arduberry and adafruit nfc sheild. Does this disable serial port?
I wonder how can I make Arduberry talk to Raspberry Pi?
Serial.begin(115200); //Start the Serial at 9600 baud
if(Serial.read()=='s') //If 's' is recieved, send the data back
int sensorValue = analogRead(A0);
Serial.println(sensorValue); //Send 'hi' followed by the analog read value
