In order to begin that journey, it is necessary to provide a `LocalEV3` support.\r\n\r\nSome examples using `LocalEV3`\r\n\r\n```java\r\nBrick brick = BrickFinder.getLocal();\r\nAudio sound = brick.getAudio();\r\nsound.systemSound(0);\r\n\r\nRegulatedMotor left = new EV3LargeRegulatedMotor(brick.getPort(\"B\"));\r\nRegulatedMotor right = new EV3LargeRegulatedMotor(brick.getPort(\"C\"));\r\n\r\n// get a port instance\r\nPort port = LocalEV3.get().getPort(\"S2\");\r\n\r\n// Get an instance of the Ultrasonic EV3 sensor\r\nEV3UltrasonicSensor sensor = new EV3UltrasonicSensor(port);\r\n\r\nGraphicsLCD g = LocalEV3.get (). GetGraphicsLCD ();\r\n\r\nBrickInfo[] bricks = BrickFinder.discover();\r\n\r\nfor(BrickInfo info: bricks) {\r\n   Brick brick = new RemoteEV3(info.getIPAddress());\r\n   brick.getAudio().systemSound(0);\r\n}\r\n```\r\n\r\n**Article:**\r\nhttps://sourceforge.net/p/lejos/wiki/Remote%20access%20to%20an%20EV3/\r\n\r\nRelated issue:\r\nhttps://github.com/ev3dev-lang-java/ev3dev-lang-java/issues/524\r\n\r\n**References:**\r\n\r\nBrick Capabilities:\r\n\r\n- [x] https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/blob/master/ev3classes/src/lejos/hardware/ev3/LocalEV3.java\r\n- [x] https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/blob/master/ev3classes/src/lejos/hardware/ev3/EV3.java\r\n- [x] https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/blob/master/ev3classes/src/lejos/hardware/Brick.java\r\n- [x] http://www.lejos.org/ev3/docs/lejos/hardware/Audio.html\r\n- [x] http://www.lejos.org/ev3/docs/lejos/hardware/Sounds.html\r\n- [x] http://www.lejos.org/ev3/docs/lejos/hardware/lcd/GraphicsLCD.html\r\n- [ ] https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/blob/master/ev3classes/src/lejos/internal/ev3/EV3LCDManager.java\r\n- [x] http://www.lejos.org/ev3/docs/lejos/hardware/Power.html\r\n- [x] http://www.lejos.org/ev3/docs/lejos/hardware/port/Port.html\r\n\r\nWifi capabilities:\r\n\r\n- [x] https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/blob/master/ev3classes/src/lejos/hardware/BrickFinder.java\r\n- [x] https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/blob/master/ev3classes/src/lejos/hardware/Wifi.java\r\n- [x] https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/blob/master/ev3classes/src/lejos/hardware/LocalWifiDevice.java\r\n- [x] https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/blob/master/ev3classes/src/lejos/internal/io/NativeWifi.java\r\n\r\n---\r\n\r\n**Offtopic examples:**\r\n\r\n- https://github.com/bartgerard/alpha/blob/master/robot/service/src/main/java/be/gerard/robot/LejosExperiment.java\r\n- https://github.com/david78k/EV3/blob/master/ev3-lejos/src/RemoteControl.java\r\n\r\n---\r\n\r\n- https://github.com/ev3dev-lang-java/lejos-ev3-code-mirror/tree/master/ev3classes/src/lejos/remote/ev3","author":{"url":"https://github.com/jabrena","@type":"Person","name":"jabrena"},"datePublished":"2020-12-29T20:38:48.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/771/ev3dev-lang-java/issues/771"}
