TEchnology
The Brick Status Light that surrounds the Brick Buttons tells you
the current status of the EV3 Brick. It can be green, orange, or red,
and can pulse. Brick Status Light codes are the following:
+ Red = Startup, Updating, Shutdown
+ Red pulsing = Busy
+ Orange = Alert, Ready
+ Orange pulsing = Alert, Running
+ Green = Ready
+ Green pulsing = Running program
You can also program the Brick Status Light to show different colors
and to pulse when different conditions are met (learn more about
using the Brick Status Light Block in the EV3 Software Help).
