code, circuits, & construction

I’ve been looking for simple ways to graph the data from a sensor attached to a microcontroller lately, because it’s such a necessary activity if you want to look at sensor data over time. Using Apples Grapher program, which comes with OSX, I found a simple way that involves only four lines of code on an Arduino or Wiring microcontroller, and produces graphs like this:

Rosie Daniel wrote a nice piece of Arduino code to control an iPod. Rosie used a hacked iPod remote to connect her Arduino to the iPod. The remote’s AUD connection is its data in connection, which is connected to the Arduino/Wiring board’s data out. The iPod’s power (VCC) and Ground are connected to the power and ground of the microcontroller. Then this code works.

Thanks to Rosie for writing this:
