h3. Data Acquisition (DAQ) System

The items in the DAQ system are described on the "wiki":https://opendesignengine.net/projects/shepard-ts/wiki/Detailed_Design_v1_0#Data-Acquisition-DAQ-System .

* The "Arduino Uno":http://arduino.cc/en/Main/ArduinoBoardUno used in this project was purchased from "Radio Shack":http://www.radioshack.com/product/index.jsp?productId=12268262 , but can also be purchased from vendors like "SparkFun":https://www.sparkfun.com/products/11021 . It can also be purchased from the "Arduino Store":http://store.arduino.cc/ww/index.php?main_page=product_info&cPath=11_12&products_id=195 for around the same price if you are willing to wait 15 days shipping time. The Uno used in the version 1.0 test stand was purchased at Radio Shack.

* The "Arduino ProtoShield":http://arduino.cc/en/Main/ArduinoProtoShield used in the version 1.0 of the test stand was a true Arduino product, and was purchased at Radio Shack for about $20. Not all Radio Shacks will have the ProtoShield in stock though. The ProtoShield can be purchased from the "Arduino Store":http://store.arduino.cc/ww/index.php?main_page=product_info&cPath=11_5&products_id=203 for around $10 more than you'd pay from U.S. based vendors. Similar boards can be purchased from many vendors including "AdaFruit":https://www.adafruit.com/products/51 for $20 including shipping. 

* The "Force Sensing Resistor (FSR)":http://www.trossenrobotics.com/store/p/6496-1-5-Inch-Force-Sensing-Resistor-FSR-.aspx used in version 1.0 of the test stand was purchased from "Trossen Robotics":http://www.trossenrobotics.com
