help with arduino projects

by msavu on Mon Dec 03, 2012 7:07 pm

Hi!
I am a sculptor and I want to create 3 interactive pieces: 1. motion triggered fan; fan speed variable.
2. motion triggered music/sound other than alarm; it has to be pleasant.
3. motion triggerd servo-motor.
I need to know what components I have to buy, the circuits and the Arduino codes.
Please help!

Motion detection is typically done with a PIR sensor. https://www.adafruit.com/products/189
These are pretty easy to use, and there are many example projects linked in the tutorial here: http://www.ladyada.net/learn/sensors/pir.html

You probably want to start with an Arduino and a PIR sensor.
There are various types of fans and they require different types of controllers. What kind of fan did you have in mind?
The Wave Shield is a good way to play sound files: https://www.adafruit.com/products/94
There are several types of servos. The "standard" servo is a good general purpose one. https://www.adafruit.com/products/155

Thank you for your answer!
I need the simplest small fan which can be used in the PIR-Arduino circuit. Any sugestions?

Computer fans are pretty easy to drive. Most take 12v DC there are some 5v DC fans too. Either can be controlled from an Arduino pin using a transistor.
