Using Johnny-Five with Grove's Moisture component on the Intel Edison Arduino Breakout. This shield and component will work with any Arduino pin-out compatible hardware platform.
Run this example from the command line with:
node eg/grove-moisture-edison.js
var five = require("johnny-five");
var Edison = require("edison-io");
var board = new five.Board({
io: new Edison()
});
board.on("ready", function() {
// Plug the Moisture module into the
// Grove Shield's A0 jack
var moisture = new five.Sensor("A0");
// Plug the Relay module into the
// Grove Shield's D6 jack.
var relay = new five.Relay(6);
moisture.scale(0, 100).on("change", function() {
// 0 - Dry
// 50 - Wet
if (this.value < 20) {
if (!relay.isOn) {
// Turn on the water pump!
relay.on();
}
} else {
relay.off();
}
});
});
