For my project last week I intended to play with sensors and textiles. I created a little system where you blew into a ventilator that produced a certain amount of voltage. This voltage was read by Arduino and gave a series of values depending on the intensity of the wind. When the value went between 100 and 300 one motor turned on one direction, when it went over 300 it changed direction and had a 3 second delay on this direction. The second motor turned on when the value was over 200. If the value went under 100 they both turned off.

More than anything it was challenge to make the code, and be able to see reactions in a mechanical way. But it was also interesting working with H bridges, to be able to manipulate multiple motors, and multiple directions.
