Ideas - Light Sensor

During the workshop I have been thinking what could be possible to do for the second assignment. At the moment I am thinking of using some kind of sensor to control a light in a room.

I am not sure yet what sensor I would be using either a,

Sensor, that reacts to sound (clapping)

Sensor, that reacts to movement.

I have sketched a schematic drawing how the setup might look,



We have already played a little bit with one of the sensors today that reacts to movement. On our first test we had it connected to a analog input and we did get some readings from it put they were pretty random.

The next step might be to connect it to a digital input and just to retrieve a 1 (on status) or 0 (off status) from it when it detects movement.
