46  Using Arduino / Project Guidance / Project: Laser Harp - simpler idea on: July 22, 2012, 06:53:23 pm
Hey Guys  smiley ... Need your advice on this idea of mine  smiley

> Maybe you've seen (and i think you have) the LASER HARP project on the net, well i wanted to build something similar to that but using more simpler and i hope more cheaper components and parts.

> I plan on proposing it as a project. About the Laser part of the project, i plan on using a simple laser pointer placed to point upward then aligned on top of it would be a photo-diode.

> the Laser pointer and the photo-diode will act as the "Strings" to the Harp, and there will be 8 of this for the 8 notes.

> So what do you think? oh and some advice on what speaker or speakers i can use for this, but i'm hoping to use only one speaker to produce all of the eight note.

> Hope you guys can give your thoughts about this... tnx  smiley-lol
47  Using Arduino / Project Guidance / Project: Smart Phone controlled Electric Fan on: July 19, 2012, 08:53:24 pm
Hi Guys, Just new here...  smiley-sweat don't know if i posted this in the right forum topic so i'm open to any corrections and guidance if you can give me  smiley-lol...

I'm in my last year in Computer Engineering and one of my project proposals is the Smartphone controlled Electric Fan.
The idea is basically that i have control over the movement of the electric fan, if I want it to face left or if I want it to face right and so forth.

I have a Samsung GT-15530 phone. This is what i plan to use for this project.
I plan on making a program that can be installed into the phone, for Android of course.]
The program displays the controls to the fan.

Another function i want to put into this is that the electric fan will be able to track where the phone is (and the owner of the phone is as well) and automatically face itself towards the direction of where the phone(owner) is.


So basically:
The program displays - Left Button, Right Button, and Automatic Follow Button
Wireless medium - Bluetooth

so the question:

Can I do this on a Arduino?
