I measure the voltage at the mote. To see the current consuption by the
mote, I connected the (+) terminal of the lab power supply to the
resistor, the I connected the resistor to the (+) terminal of the mote.
Next I connected the (-) terminal of the lab power supply to the GND of
the mote. At last I connected (+) terminal of the oscilloscope to the
(+) terminal of the resistor and (-) terminal of the oscilloscope to the
(-) terminal of the resistor.

(the red and black/red wires belong to the power supply, while the probe
belongs to the oscilloscope.)
