Testing Light Sensors

We have experimented with a range of light inputs and light sensors; the light changes the amount of resistance within the circuit; thereby affecting the tone or sonic parameter. When working with this aspect we are looking at the following dynamics;

>responsivity to light. How sensitive they are to changes in brightness

>width of response

>sound outputted (for example a Theremin like slow swoosh, or a rapid staccato beat)

Here are some of the light sensors we are testing.

Light Dependent Resisters
