set Remote Channel
Set the remote infrared signal channel for an infrared sensor.
sensors.infrared1.setRemoteChannel(InfraredRemoteChannel.Ch0)An infrared sensor connected to the LEGO® MINDSTORMS® Education EV3 can receive messages (signals for button events) from a remote infrared beacon. In order for the sensor to know which beacon to receive messages from, a channel is used. The beacon has a switch on it to select a particular channel to transmit on. The sensor needs to know which channel to receive (“listen” for) messages from the beacon.
A sensor is not automatically set to listen for infrared messages on a channel. To avoid confusion on which sensor receives signals from a beacon, each sensor (if you have more than one), sets a remote channel for itself. The channel number matches the channel selected on the beacon.
Parameters
- channel: the channel for the infrared sensor to “listen” on. You can choose to use one of 4 channels:
0,1,2, and3.
Example
Select channel 2 on an infrared beacon. Set the remote channel for infrared sensor infrared 3 to channel 2. Wait for the center button press on the beacon using channel 2.
sensors.infrared3.setRemoteChannel(InfraredRemoteChannel.Ch2);
sensors.remoteButtonCenter.pauseUntil(ButtonEvent.Pressed);
brick.clearScreen();
brick.showString("Center button on", 1);
brick.showString("channel 2 beacon", 2);
brick.showString("was pressed.", 3);
