Arduino Demo Video

It is a small collection of demonstration videos for the teaching of Arduino and physical computing.

Arduino with solenoid

It is a demonstration for the class Virtual Touch (http://va3470.wordpress.com) to introduce the use of a solenoid with Arduino and an IC ULN2803A.

It is a proof of concept work. I use a PureData patch to control an Arduino board with PWM output to drive a small computer fan. The load is managed by a ULN2803A IC. The blowing power is not linearly proportional to the numerical value sent from PureData. It is quite difficult to sustain a floating position in the middle of the air.
