Swinging Structure Sounds is a sound creating composition of motorised structures. These three structures consist out of different materials, patterns, concentrations and motions to visualise differences in the tone ranges. Using the structures particular shape and behaviour enabled the team to translate the change of light into sounds via light sensors.
The tones being created depend on different factors, such as the distance between light and structures, light intensity (experimented with space and resources), speed at which the structures turn and the movement of light through the room, as well as the interactions between the structures themselves.
The more light the objects reflect on to the sensors, the louder the tone is. The faster the structures turn, the quicker the change of tones is, caused through uneven shapes. Due to the change of the light`s angle the structures can compose sound variations.
Before we decided on which shapes and materials we wanted to work with, we tested various prototypes and objects around us to find out about their characteristics in patterns, concentrations and sound variations.
For Liliana and myself it was the first time actually working with an Arduino. We decided to approach the small one night task together as we wanted to learn the basics of Arduino and felt that we could best do so with a person that does not know anything about Arduino as well.
We started by combining one light sensor, one piezo and one motor with different structures attached to it and wanted to find out how we could create different tones. We then decided on three structures that were most diverse to create a range of different tones. We built a box and placed all the elements we worked with before multiplied by three and hooked up three potentiometers to control the speed of the motors.
It was a long and late night, but we were able to push our own boundaries and learned more than we expected while having a great time.
