Data for the LDR from the Arduino is almost perfectly read.

ISSUE: some messages are split (possibly because the input buffer is
full mid-message)
Added Python scripts under /Assets/Python for automating serial
communication.

Added new Arduino sketch: BT_power_switchable (digital pin 8 powers
on/off the BT module
Added new wire-schematic: board with LDR + transistor/buffer (to power
the BT module)

ISSUES: the Python scripts are not finished
		the COM ports remain opened unless PC is rebooted, possibly because
the Python scripts don't close them properly

TODO: Python script that sends 's' or 'f' to EVERY arduino connected
TODO: check if the Baud-Rates of the BT and COM-Serials are correct
(i.e. one should be higher than the other)
