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.
