Look how far we've come.
With the release of the new Proximity class, components which measure distance to obstruction now share a common home. Components that were formerly spread across Infrared, Sonar, and Ping classes can be found in one place, and used with a more consistent API. The new API also makes implementing new components even easier, and we've been able to add a handful of new proximity components already.
Check the API docs for a list of supported components, and how to use them.
var five = require("johnny-five");
var board = new five.Board();
board.on("ready", function() {
var proximity = new five.Proximity({
controller: "GP2Y0A21YK",
pin: "A0"
});
proximity.on("data", function() {
console.log(this.cm + "cm", this.in + "in");
});
proximity.on("change", function() {
console.log("The obstruction has moved.");
});
});
All distance to obstruction devices now share this API, with the only changes being the controller and pin properties.
This change will not affect existing code, but IR.Distance, IR.Proximity, Sonar, and Ping have been deprecated and will be removed when Johnny-Five reaches 1.0.
Please report any issues here.
