CylonJS ?
Why ?
You like NodeJS, but don’t like calling external shell scripts ?
There’s a clean solution : CylonJS !
How ?
Make sure you have the last version of the libmraa :
https://github.com/intel-iot-devkit/mraa
Install the NodeJS module :
npm install cylon-intel-iot
Examples
Blink a LED
Blink a LED on pin #13
var Cylon = require('cylon');
Cylon.robot({
connection: { name: 'edison', adaptor: 'intel-iot' },
device: {name: 'led', driver: 'led', pin: 13 },
work: function(my) {
every((1).second(), function() {
my.led.toggle();
});
}
}).start();
Control a Servo
Control of a Servo
var Cylon = require('cylon');
Cylon.robot({
connection: { name: 'edison', adaptor: 'intel-iot' },
device: {name: 'servo', driver: 'servo', pin: 3 },
work: function(my) {
var angle = 45 ;
my.servo.angle(angle);
every((1).second(), function() {
angle = angle + 45 ;
if (angle > 135) {
angle = 45
}
my.servo.angle(angle);
});
}
}).start();
This code make a servo motor switch
every second from 45 to 90 to 135
degree.
This servo of this exemple is plugged on
the pin 3 of the Edison board.
Analog Read
Analog Read on A0
Cylon.robot({
connection: {
name: 'Edison',
adaptor: 'intel-iot'
},
device: {
name: 'sensor',
driver: 'analogSensor',
pin: 0,
lowerLimit: 100,
upperLimit: 900
},
work: function(my) {
var analogValue = 0;
every((1).second(), function() {
analogValue = my.sensor.analogRead();
console.log('Analog value => ', analogValue);
});
my.sensor.on('lowerLimit', function(val) {
console.log("Lower limit reached!");
console.log('Analog value => ', val);
});
my.sensor.on('upperLimit', function(val) {
console.log("Upper limit reached!");
console.log('Analog value => ', val);
});
}
}).start();
Conclusion
CylonJS is great
NodeJS / CylonJS
NodeJS programming style is perfectly adapted to IoT. That’s why it is so popular.
But you need a good library to interact with the GPIO : CylonJS.
CylonJS is great and available today. It targets robotics but can be used for anything
IoT related.
Keep a eye on future NodeJS modules. You may see another one taking advantages of
unique Edison features. But we propose you use CylonJS today.
