This integration will connect an Arduino to a computer. An application on the computer will consume web service which will check ServiceNow for Critical (P1) incidents in a New status.

This integration will connect an Arduino to a computer. An application on the computer will consume web service which will check ServiceNow for Critical (P1) incidents in a New status.

If the web service returns an incident, an LED attached to the Arduino will light up red. A user can hit a button which will temporarily light up the LED blue and assign the incident to Fred Luddy in the CAB Approvers group.

• Download and install the Arduno IDE: http://arduino.cc/en/main/software
• Download and install Node.JS: https://nodejs.org/download/
• Download and extract the Zip (the button on the right side of this). Extract to your user directory.
• Install NODE modules.
Open a command prompt/terminal
Type this and hit enter: npm install

Wire the Arduino based on this diagram Open Arduino IDE Download this sketch.. HERE ..and paste in to the Arduino IDE In the Arduino IDE, hit the Arrow icon (upper left, to the right of the check) to upload the script to the Arduino

• In your preferred text editor open config.js (it is one of the files in the Zip file).
• Update the instance URL with your instance name
• Update username and password with an Admin username and password.
• Update the serialport variable. You will find this by opening the Arduino IDE, going to Tools -> Port. It will say something like "/dev/tty.usbmodem1451 (Arduino Uno)" or "COM4 (Arduino Uno)". In this example, the com port is "/dev/tty.usbmodem1451" or "COM4"
• Save the file.

• Log in to your ServiceNow instance
• Update the web services properties (go to System Web Services -> Properties)
• Set following check boxes to "Yes" leave all other unchecked
Require authorization for incoming RSS requests
Require basic authorization for incoming SOAP requests
Require authorization for incoming WSDL requests.
Use unique targetNamespace for WSDL definition.

• After confirming you do not have any unassigned, P1 incidents in a "new" status, on your instance.
• Open the command prompt/terminal.
• type "node arduino".
• In your ServiceNow instance, create a new, unassigned, P1 instance.
• Wait for the light connected to the Arduino to turn red (it should be just a few seconds after you save the incident)
• Push the button. The light on the arduino will turn blue.
• Go back to your ServiceNow instance. Confirm that the incident as been assigned.
