+
+  You can receive x and y coords for joystick movement within App.
+
+  Datastream setup:
+    Virtual Pin V0, type: String
+
+  App dashboard setup:
+    Add Joystick widget, select mode: Advanced, attach it V0
+
+  NOTE: Advanced mode means device will receive both x and y on a single Datastream
