The hello world application for NodeBots is the customary blink of a LED.
On your particle core bread board take a led red or green and place the long end into the D7
and the short end into the GND
slot of the breadboard.
Then create a folder on your computer called jf-helloworld
and cd into that folder.
Enter the following commands:
# init as an npm project - default through the prompts
npm init -y
npm install johnny-five --save
npm install spark-io --save
Create a file called index.js
var Spark = require('spark-io')
var five = require('johnny-five')
var board = new five.Board({
io: new Spark({
token: process.env.SPARK_TOKEN,
deviceId: process.env.SPARK_DEVICE_ID
})
})
board.on('ready', function() {
var led = new five.Led("D7")
led.blink()
})
Finally setup your deviceId and access token as env
variables:
export SPARK_TOKEN=[access token]
export SPARK_DEVICE_ID=[device id]
Now you are ready to run you app:
node index.js
!!! Congrats you should see a LED Blink !!!
[ctrl-c] will close the app.
