Download this software to your Satellite, and unzip it: [https://ccrma.stanford.edu/courses/250a/labs/lab5.zip lab5 zip].
+
First start up your kit
 +
Connect your Satellite CCRMA kit to your laptop and boot it.
 +
* Use a terminal window to login to Satellite CCRMA as usual using the command <code>ssh -XY ccrma@192.168.105.106</code> with the password <code>temppwd</code>.
 +
* Check that your kit has access to the internet through you laptop. You can do this by trying to ping Bing. Run the command <code> ping bing.com</code>/ If it is successful, it will tell you how long it takes to send a packet from your Satellite CCRMA kit to Bing and back.  
  
−
Flash your Arduino with Standard Firmata. (See [https://ccrma.stanford.edu/wiki/Talk:250a_Microcontroller_%26_Sensors_Lab_Pd#Prepare_Arduino this link] if you forget how.)
+
Now copy the lab files to your kit.  
 +
* At the command line in the terminal window, type <code> wget http://ccrma.stanford.edu/courses/250a/labs/lab5.zip </code> to download the lab5 files to your Beagleboard.
 +
* Unzip the file: change into your ~/ directory, and type <code>unzip lab5.zip</code>. This should create a folder called lab5/ with all the files you need.  
  
−
Set up your accelerometer so that the XYZ outs are going into A0, A1 & A2.
+
Run the command <code>arduino &</code> to start the Arduino IDE. 
 +
*Use the Arduino IDE to flash your Arduino with Standard Firmata. (See [https://ccrma.stanford.edu/wiki/Talk:250a_Microcontroller_%26_Sensors_Lab_Pd#Prepare_Arduino this link] if you forget how.)
 +
 
 +
Set up your accelerometer:
 +
* if you haven't soldered your header pins to your accelerometer board, do this now (ask the TA for help if you haven't soldered before). (see [https://ccrma.stanford.edu/wiki/Talk:250a_Microcontroller_%26_Sensors_Lab_Pd#Tilt_control_with_an_Accelerometer_.28Optional.29 this previous lab) for details.
 +
* connect 5V and GND to the Vin and G pins, respectively.
 +
* connect XYZ outputs are going into the Arduino analog pins A0, A1 & A2.
