IR Proximity

Breadboard for "IR Proximity"

Fritzing diagram: docs/breadboard/ir-proximity.fzz

 

Run this example from the command line with:

node eg/ir-proximity.js

var five = require("johnny-five");
var board = new five.Board();
var controller = process.argv[2] || "GP2Y0A02YK0F";

board.on("ready", function() {
  var proximity = new five.IR.Proximity({
    controller: controller,
    pin: "A0"
  });

  proximity.on("data", function() {
    console.log("inches: ", this.inches);
    console.log("cm: ", this.cm);
  });
});

// Run this program with a device model for the controller:
//
//    node eg/ir-distance GP2Y0A02YK0F
//
//    You may also use the model number printed on the
//    device itself. eg
//
//    2Y0A21
//    2D120X
//    2Y0A02
//    OA41SK
//
//    Without a specific model number, the readings will
//    be wrong (unless you've connected a GP2Y0A02YK0F/2Y0A02)
//
// Valid models:
//
// - GP2Y0A21YK
//     https://www.sparkfun.com/products/242
// - GP2D120XJ00F
//     https://www.sparkfun.com/products/8959
// - GP2Y0A02YK0F
//     https://www.sparkfun.com/products/8958
// - GP2Y0A41SK0F
