Example of Adafruit Ultimate GPS on serial.
Fritzing diagram: gps-adafruit.fzz
Run this example from the command line with:
node eg/gps-adafruit.js
const { Board, GPS } = require("johnny-five");
const board = new Board();
board.on("ready", () => {
/*
* This is the simplest initialization
* We assume SW_SERIAL0 for the port
*/
const gps = new GPS({
breakout: "ADAFRUIT_ULTIMATE_GPS",
pins: {
rx: 11,
tx: 10,
}
});
// If latitude, longitude, course or speed change log it
gps.on("change", position => {
const {latitude, longitude} = position;
console.log("GPS Position:");
console.log(" latitude : ", latitude);
console.log(" longitude : ", longitude);
console.log("--------------------------------------");
});
});
