dynamically updates the data in our blank <span> tags defined below.

poll() is set to be called every pollRate (defaulted to 1000)

milliseconds.

Whew! Hopefully all of this stuff is easy enough to pattern-match and

modify as you please. To make some other information stream to the

webpage, you have to:

1. Edit the imp Device code to send the desired data to the agent. Use

the agent.send() function to do this.

2. Edit the Agent code in two places:

1. Read the data in from the imp in the device.on() function.

2. In an HTTP request handler, send the data out as a JSON

string.

3. Add something in the AJAX success function to look for the correct

JSON “key” and “value” combination. Then do something with that

data.

4. Add a location in the HTML body to show the data. E.g.

Give it a try! It sounds like a lot of work, but most of the constructs are

already there for you to quickly add new displayable data. You could print

the imp’s measured RSSI, or do some math on the analog input reading to

turn it into a voltage.

Resources & Going Further

Now that you know how to hook up the imp and its Breakout, what project

will you be making with it? Will you be adding to the “Internet of Things”?
