LEDs

The Radar Shield2Go comes with four different LEDs.
The green PWR LED indicates that the +3V3 pin is connected to a power supply. The blue motion LED indicates
any movement detected by the radar, while the red direction LED indicates an approaching or departing object.
Table 9 shows the behavior of the motion (blue) and direction (red) LEDs, in case the MMIC radar detects an
object's presence or its direction of movement.
