Hi there,
I scored a bunch of 5x7 LED matrices from eBay, for a scolling LED sign project. I found the data sheet and thought step 1 would be to familiarize myself with the pins and trying to light up individual LEDs. I've using jumper leads on my breadboard so that I cold rationalise the pinouts to a line of jumpers for rows and a separate line for columns.
So far so good, except for the fact that its ended up a mass of wires. thats fine as I'm only playing with it at the moment, but I cant see how I would scale it up to a row of these matrices to make a sign without it being a messy tangle of wires.
I dont want to use a custom PCB really for a one off, and thats a bit advanced for me at the moment anyway, but do you guys have any advice on how to arrange such a thing using stripboard so that I can address the rows/cols seperately when I come to design the rest of the electronics?
I suppose it will be helped by the fact that the required multiplexing, means rows will be wired together.
Hope that makes sense.
Thanks
