user37915: I'm trying to make an interactive installation where I have 6 pressure pads that each control an Air Fan. The pressure sensors ideally will be on chairs.
I would like the changes in pressure to change the speed of the Air Fans.
What is the easiest way for me to do this? Can I do it with just an Arduino?
I haven't bought anything yet as I'm assessing what the best route is.

user27653: If you mean this kind of sensor:
The sensor is a simple microswitch with mechanical pressure switching point, which means your Arduino just needs to monitor 6 digital inputs. That is entirely possible.
The sensors would have one side connected to ground, and the other to a GPIO pin on the Arduino, with a pull-up resistor to 5V. Your code should just check each of the 6 GPIO inputs. If the pressure sensor is tripped, the input would be LOW, otherwise HIGH.
