Arduino Light Display With Vixen
send me your code and I will take a look at it for you. I am working on a four line display using the I2C and have been sending text to easy.
Check out my page, I have a step by step with photos that will help you.
Try using express PCB software it is also free, or if your happy with yours that is fine too. Then buy you some heat toner transfer paper from ebay. For the top layer it is fine to print directly to the paper. But for the underside of the board print to the paper in mirror image. Clean you copper clad with steel wool. use a hot iron and iron the top layer on first. before ironing on the other side I would suggest drilling a couple of holes to align the other side before ironing it on. Then just etch it normally, there you go a nice looking PC board.
