Hey,
I want to build a user interface with some led dot matrix. I want to simulate this with arduino.
Can anyone help me where to start? What hardware do I need? I want to link at least 4 8x8 led dot matrices.
Is it also possible to use a capacitive foil with arduino? Is this doable for a beginner?
Thanks
The idea sounds feasible but you need to flesh out your requirements a bit more to be certain.
Driving a 8x8 monochrome LED matrix is easy using a MAX7219 and you can daisy chain them together to drive 4 or more matrix displays.
Capacitive foil needs a bit more explaining as there are several ways to read this. Post links to the foil your hoping to use or explain it in more detail. Is it a strip/sheet. Does it have/need a controller. ETC.
read the forum guidelines.
Try to summarize your problem with a helpful and informative subject line. Helpful subjects draw in people who might know the answer. Unhelpful ones are likely to be skipped.

================================
then, do some google to find a similar project and see if that answers some or most or all of your questions.
then use a pencil, create a flow chart or a schematic and organize your project into segments.
find and try each segment.
scan your flow chart or schematic, and post along with the code you tried.

This is pretty common. Adafruit sells everything and has sample code. Copied stuff is available from China if you are on a strict budget, but quality may suffer and compatibility is not guaranteed to the Adafruit software.
