the straight line is the voltage value of the mote batteries...and ofcourse the value will be constant .... run the oscilloscope for sufficient time... you will see a drop in the voltage level.....
zoom the voltage range of y-axis.. you might see little fluctuations.... but voltage level cant rise unless you change batteries...
