How to manage the status light colors

The status lights show whether the robot is on and whether there is a program running. When the green light is on, the robot is turned on. When the green light flashes quickly, a program is currently running.

This is the default light behavior  when we have not programmed it. From now on, if necessary, we can program it explicitly. The LED control unit is located in the green Action palette:

We can program the light
to switch on - ON mode,
to switch off - OFF mode,
or to return to flashing status as a normal operating program - Reset mode.
