pause Until

Make your program wait until a button event from a remote beacon happens.

sensors.remoteButtonBottomLeft.pauseUntil(ButtonEvent.Bumped);

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.

Parameters

  • ev: the beacon button action to wait for. The button actions (events) are:
    • pressed: the button was pressed, or pressed and released
    • bumped: the button was just bumped
    • released: the button was just released

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.

Example

Wait for a bump to beacon button center before continuing with displaying a message on the screen.

let waitTime = 0;
brick.clearScreen();
brick.showString("We're going to wait", 1);
brick.showString("for you to bump the", 2);
brick.showString("touch sensor on port 1", 3);
waitTime = control.millis();
sensors.infrared1.setRemoteChannel(InfraredRemoteChannel.Ch0)
sensors.remoteButtonCenter.pauseUntil(ButtonEvent.Bumped);
brick.clearScreen();
if (control.millis() - waitTime > 5000) {
    brick.showString("Ok, that took awhile!", 1);
} else {
    brick.showString("Ah, you let go!", 1);
}
