It can be used as a indicator for remaining battery life, voltage, water level, music volume or other values that require a gradient display. There are 10 LED bars in the LED bar graph: one red, one yellow, one light green, and the rest green. It lights up the LEDs sequentially from red to green, so the entire bar graph is lit up in the end. ==Examples== ''<span style="color:red;">No additional examples</span>'' ==Downloadable macro reference== ===<span style="font-weight: normal;"><u><tt>SetBinary</tt></u></span>=== Allows a binary value to be shown on the LEDs.
