-The camera project didn’t require any major engineering effort, but rather was a simple “mash up” of existing elements — a perfect example of the //sketching// principle of Arduino. Being Arduino-based, it’s also easy to tweak…say if you’d like a time-lapse camera rather than motion sensing. Let’s see how it’s put together!

   * A suitable power supply: either a [[https://www.adafruit.com/products/63|9V 1A wall adapter]]…or, for standalone wireless use, our [[https://www.adafruit.com/products/248|6-cell AA battery holder]] is best. For the smallest possible package, a [[https://www.adafruit.com/products/14|MintyBoost]] can also work, but provides only about two hours’ run time.
   * The usual electronic project bits and bobs: wire, soldering tools, etc.

-The aforementioned example sketches place the camera on Arduino pins 2 and 3 in conjunction with the SoftwareSerial library, keeping the Arduino’s native serial port available for communicating to a host computer. But the sketch used here instead assigns the camera to the hardware serial port for added robustness. Devices have their own independent clock sources, and baud rates always have a bit of slop…sometimes they fall out of phase and a glitch occurs, as can happen between the camera and Arduino. The hardware serial port is less prone to these errors. Not 100%, but noticeably more robust than SoftwareSerial in this regard. Maybe 1 in 100 images arrive corrupted, vs. about 10x that rate with SoftwareSerial.

 But using the Arduino’s serial port for the camera prevents us from sending debugging and status messages over USB. Instead, the LEDs on the Data Logging Shield are used…various blink patterns indicate the current status. Using the serial port also requires that the camera be unplugged when uploading sketches to the board, since it would interfere with the serial transfer.

 Next, upload the EyeFi sketch, then re-install the jumpers between pins 0-2 and 1-3. You can then either press the reset button to start the sketch, or disconnect from the computer and attach a power adapter or battery.
