Arduino Fun – Science Experiment #1

The Arduino Duemilanove board is such a fun little thing to play with.

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.

Both Scott and Toby helped out in creating a visual and audible light detector.
We used:

  • 8 Light Emitting Diodes
  • 9 resistors
  • 1 photo resistor
  • 1 piezo speaker

here is what our Arduino experimental board looked like:

We ended up creating the following C file to upload to our Arduino board to test it out. We found that in total darkness, all the LED’s are lit and there is no tone emitted. Whereas walking outside turned all the LED’s off and the speaker output a high note.

    Wow! That looks really complicated. I’m proud of you for putting it together. Just wish I knew what is was…

  2. Having read this I thought it was very informative. I appreciate you spending some time and energy to put
    this article together. I once again find myself personally spending a lot of time both reading and posting comments.
    But so what, it was still worth it!
