Hardware update: From the breadboard to soldered circuit board
The group integrated the circuit with the arduino board and bluetooth by soldering.
The new circuit has a 9V power supply and the 9V is split to two, 6V for the bluetooth and 9 V for the arduino nano3.0
The new circuit gives a much more stable signal than the old one. The reason may be the 9V supply gives more stable voltage than USB does.
