Make your own Arduino-controlled Spectrometer

There are various forms of electronic test equipment you can build with an Arduino-based circuit - however this spectrometer by Instructables member simonfrfr takes the concept of home-made equipement to a higher level. With some simple hardware, mostly derived from an old PC optical drive, you could make this in a weekend or so.

For the curious, a spectrometer is "is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials", and for the scientifically-inclined this would be a lot of fun. For a quick explanation and demonstration, check out the following video:

For complete details, check out the spectrometer project page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well. 

If you're wanting to make your own Arduino-compatible project such as the spectrometer above, you'll need an ATmega328P MCU with Arduino Uno bootloader:

This is the same Atmel AVR ATmega328P microcontroller used in the official Arduino Uno, as well as our ElevenEtherTenUSBDroid, and other boards. Perfect for building your own Arduino-compatible project directly on a breadboard or on a custom PCB, or for replacing the MCU in an existing board. Comes with the Arduino Uno bootloader pre-installed. Better still, it even has a special label stuck on top with details of the pinout, so you don't even need to look up the datasheet when connecting it up in your project!
