Hi there,
New to the forum and was wondering if anyone can help out with a project that I am planning.
Using a 5x7 LED matrix I would like to build a circuit that utilises only a 4x5 area of the matrix to display an alphanumeric character. The idea would be to display a single character (specifically 1-9 and A-D) by applying power to a separate lead for each character. I am trying to avoid computer control if possible.
Does anyone have any suggestions on how this could be put together - apologies if this is kind of a basic question but I have never worked with matrices before and thus am unsure as to how they are driven.
Any help much appreciated, davyjcrow
