I am kinda lost in the overload of new information and I want to do this project as good as possible. So what formula do I need to calculate the resistors? I have the following information about my dot matrix:
Thanks alot for clearing that up! I was also trying to find some high brightness yesterday but eventual I found out that most 1,2" dot matrix are about +/-20000?cd which is 20mcd, right? I assume if I want higher brightness I need to make my own LED matrix.
I also want to hook up two 8x5 matrix, I already have ordered 2 dot matrix's in this dutch webshop.
Thanks again Cross!
If it's also not to bright I might consider making my own.
Also I forgot to mention that I want to have a few millimeter of distance between the 2 matrix so that you can read the numbers instead of seeing a block of LED's
The resistors & jumpers are on the way with the post so the fun is about to start soon
