is Pressed

Check to see if a remote beacon button is currently pressed or not.


An infrared beacon works with an infrared sensor connected to the LEGO® MINDSTORMS® Education EV3. The beacon sends a signal over infrared with information about button presses on the beacon. The infrared sensor receives the signal from the beacon and records a button event.


  • a boolean value that is true if the beacon button is currently pressed. It’s false if the button is not pressed.

Remote channel

In order to recognize a button event signalled from a remote beacon, an infrared sensor must know what channel to listen on for messages from that beacon. An infrared sensor needs to set the channel first, then it can receive messages transmitted by the beacon. Before waiting for, or checking on an button event from a beacon, use set remote channel.


If the beacon button center is pressed, show a green status light. Otherwise, set the status light to orange.
