Proximity

If you want to build a robot, one common approach for obstacle detection is an ultrasonic distance meter. Johnny-Five has a nice module to work with proximity detectors.

Look at the following code for an example based on the SRF10 sensor:

// check_proximity.js var five = require("johnny-five"); var board = new five.Board(); board.on("ready", function() { var proximity = new five.Proximity({ controller: "SRF10" }); proximity.on("data", function() { console.log(this.cm + "cm", this.in + "in"); }); proximity.on("change", function() { console.log("The obstruction has moved."); }); });
