Scroll the text on the matrix... without any electronic components!!!

Scroll the text without using any controllers or other components on the matrix except the arduino/picaxe and the matrix, and ya dont forget the current limiting resistors!

And by using only 10 pins. In case if your matrix is 5x5. For 6x6 matrix 12 pins and so on...

For refrence look at my posts for scrolling texts

Ya you did a wonderful job my code is a bit complex and instead of binary I used digital.write fun^c everywhere.

I ll post about the code soon

congratulations winner

 

No internets?

Ok, maybe just an internet high five?

What if I refactor the code to look nicer?

Internets???

Check you last sentence, Kinda didn't understand it

Show every detail

mail me the code sample how many lines of code did you had to write?

So, I went to the electronics shop and instead of buying 25 leds I just got a led matrix. This is not some fancy matrix with integrated controller, just 40 leds in a single package. You still have a pin for each colum and row. Since this is a 5x8 matrix you need 13 pins to control it. Getting it to display and scroll LMR was easy so I went one step further and I wrote a function to scroll any arbitrary text. It is very late here so I will post the details tomorrow.

No comments!!!

well I think it is simple you do what a shifter would do but with code right?
