hello there. I'm working on my thesis project. Basically it's a sound installation. Without any interaction, it sounds pretty repetitive and sparse. I would like to connect arduino to some parameters in ableton (no problems here, since there's a special plugin directly builty in ableton live). these parameters should be modulated according to the interaction. since it makes sense with the concept behind my thesis, the idea is to put some chairs in a room. when people sit on these chairs, the track changes, becomes more dense and dynamic sound-wise.
therefore my question is: which is the best way to connect chairs to arduino? i need these values that ableton receives to be 1-100, and not an on-off (0-1) switch. so i thought about pressure sensors, maybe under the legs of the chairs.
any ideas?
i hope i explained myself. thank you
im willing to explain further if necessary
How about air fill cushions with pressure sensors to sense the air pressure?
that's not a bad idea but maybe not so nice too look at? or am i imagining it wrong?
An FSR under the leg of a chair would easily tell you is the chair is occupied. You could use a small radio at each chair to send an ID code and occupied or not signal to a master radio.
why are you mentioning a radio? i'm programming the tracks that are gonna play when you sit. could you please tell me what does FSR stand for? thank you
Force Sensing Resistor. They do just that, but not like a load cell. They are good for sensing the presence of a force or the rough magnitude of a force. FSRs are not usually linear nor is repeatability very good. FSR must be part of a resistor voltage divider.
Regarding radios: never mind. I made an apparently erroneous assumption about the big picture.
Regarding FSRs: see the reply from @groundFungus
