 # arduino-accelerometer-and-data-logger
 
-An arduino based accelerometer with SD data logger shield.  
+This project was intended to create a low cost accelerometer with portable DAQ system.  The system consisted of a three axis accelerometer, an Arduino and a data logging shield.  When the user presses the start/stop (on/off) button the Arduino will start logging the output from the accelerometer.  
+
+The following is the parts list:
+
+*[+/- 3G triple axis accelerometer ($15)](https://www.adafruit.com/products/163)
+*[Illuminated latching on/off switch ($2)](https://www.adafruit.com/products/1478)
+*[SD Data logging shield for Arduino ($20)](https://www.adafruit.com/products/1141)
+*[Arduino Uno ($25)](https://www.adafruit.com/products/50)
+*[SD card]
+*[Shield stacking headers ($2)](https://www.adafruit.com/products/85)
