"Call web service" tag

Learn the technical principles necessary to create VIs that can call Web services which return information in the form of JSON strings.
Form a query string as a URL, retrieve the JSON string served by the Web service, and parse the JSON string to extract useful information.
Host a web service on the Academic RIO Device to serve the states of onboard sensors (pushbutton and accelerometer) and system information (date, time, host name, and IP address), and to control the onboard LEDs based on a user-selected LED hex code.
