1  Using Arduino / LEDs and Multiplexing / Re: 8*8 dot matrix controlled by Nintendo DS Trackpad. on: May 19, 2011, 08:13:20 am
I've searched and found the correct connections for it, thanks for the hint.

For the coding, this is the closest I can find http://arduino.cc/forum/index.php/topic,14999.0.html which has been helpful, but I still feel a little out of my depth. Any hints on coding?

2  Using Arduino / LEDs and Multiplexing / 'Throbbing' 8*8 dot matrix. on: May 19, 2011, 08:07:01 am
I'm currently using an 8*8 dot matrix, I hope to make the lights throb or pulse in unison. The time between each pulse and the brightness is unimportant, it's just to be used for a 'proof of principle' prototype.

I currently have the setup suggested by arduino: http://arduino.cc/en/Tutorial/RowColumnScanning , is this correct? Any help with the code would also be greatly appreciated.

Hi guys. Apologies in advance if any of these questions seem a little simple or misguided, I'm completely new to electronics and programming.

For a university project I'm hoping to use a Nintendo DS touchpad to control the movement of lights on an 8*8 dot matrix.

The main components I have so far are:
-Arduino Uno
-Nintendo DS touchpad: http://images.excheap.com/imagecache/nintendo-ds-lite-ndsl-touch-screen-repair-parts-bl-1943310267.jpg
-8*8 dot matrix (anode) http://www.lc-led.com/View/itemNumber/193

I have pretty much found the exact coding and setup for the system here: http://allthemods.com/project.php?id=342&page=1

In the example however, a laptop touchpad is used, with 5 output (?) connections; +5v, NC, Data, Clock, Ground. As far as I'm aware they're all used in the code and setup. Is it possible to still use the Nintendo DS touchpad even though it has 4 connectors?

Also, I'm aware that I'll have to use an LED display driver, but there is no schematic diagram to show the exact setup. If anyone knows of any simple ways of setting this up or any circuit diagrams I'd be very grateful.

Once again, apologies if the information provided is a little basic. Thankyou in advance for any help provided.

S.
