def get_voltage():
    """
    Reads the digital output code of the MCP3021 chip on the BrickPi+ over i2c.
    Some bit operation magic to get a voltage floating number.

    If this doesnt work try this on the command line: i2cdetect -y 1
    The 1 in there is the bus number, same as in bus = smbus.SMBus(1)
    Google the resulting error.
