Items Needed:

• 2 Xbees configured for comms. If you need to configure them see this tutorial: Xbee Basic Setup

• 2 mbed Application Boards

• CoolTerm Terminal (or equivalent terminal ability): Download Home Page (Windows 64-bit link)

• MaxBotix LV MaxSonar® EZ™ Series Product Page Any EZ0-4 will work, choose based on application and sensitivity requirements.

Steps

1. 1 Set Xbee radios into designated spot on mbed Application Boards and plug into computer:
2. Verify that the computer recognized the boards by checking the Computer section of your file browser for Devices with removable Storage. They will be named generically for the appBoard, I recommend you change their names based on their corresponding Xbee's configuration. I will be following the assumption that they are correctly named for the remainder of the tutorial.
3. Assemble the range finder as shown below on the End Device application board.

• Power with 3.3v from appBoard
• Ground to appBoard
• Connect AN to p17

1. Download the following code onto the End Device appBoard:

   Import programanalogRangeSend

   send analog info from MaxBotix range finder with xbee. Download onto the End Device with the sensor.
