Amber is a mix of red and green, just buy a bi-colour and then mix those two.

LED drivers

OK! I've got the bi-color LED matrices. Can anyone please tell me a cheap bi-color LED driver. My display would comprise of 8 16x16 LED matrices.
They are all bi-color. I searched in farnell and digi-key. They've got some drivers but is there anyone who has used them. Please help me.

What about Maxim?

I know I've got to use more than one LED driver and also I've got to have a micro-controller as well.

MAX7219-7221

Which microcontroller do you plan on using?
A pic16f886 might do the job.

This is the one I use! Thanks for the info!

But I would need 8 of those for one 16x16 since I'm using bi-color.
