Adding a Serial. println() method facilitates debugging

issue: scientifichackers/ampy#118

print("Temperature: ", temperature) ====> Serial. println("Temperature: ", temperature) ?

If you've already got /dev/ttyACM0 open in minicom, ampy won't be able to interact with the board since the serial port is in use.

Thank you very much @scruss
Correct. Close minicom, and the print() method can work properly. This is due to my incorrect operation sequence.
