For those wanting a simple and interesting project to introduce someone to the world of Arduino - this could be the ticket. Instructables user 'gwarbeh' has created a theremin (a musical instrument that is played without physical contact) using a light-sensor, Arduino and headphones for audio output. You can make it in less than half an hour, and the results are quite good - for example:
For all the details and Arduino sketch visit the project page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
Looking for a light sensor? Although it can be tempting to use a light-dependent resistor, they're fragile and can give varying results. Instead - consider our LIGHT: light sensor module based around the digital TEMT6000 sensor. It gives consistent and reliable readings, and is incredibly easy to use with our Getting Started guide.
