The 555 solution sounds very good, and it's easier for me to calculate the delay. I'll go that way.

Thank you so much.

Hi, thanks for your answer it's Arduino Uno original. I have no idea how to change the fuses (looks like I have to dig a little bit into it).
If I use the capacitor solution, is there no side effect, like resets when I don't want to?

Sorry, but I couldn't stop thinking about this:

4  Using Arduino / General Electronics / plugging issue on: December 07, 2012, 07:09:31 pm
Hi, I'm trying to make an Arduino based device which goes plugged to the power outlet.
I'm repurposing one of those "USB outlet" cell phone chargers (like the one in the pic) since I have a lot of them.



But there is a problem:  If I plug the charger, and then the arduino, everything works perfect. But, if I connect first the arduino to the charger, and then to the power outlet, the arduino won't start until the reset button is pushed.

I've tried to solve it adding a delay in the void setup() hoping that it allows some "power stabilization" (I know, not even me buy this BS)
I was thinking in some kind of capacitor in order to delay the power feed (is it even worst BS?)

thanks for reading!

tal vez te resulte más sencillo usar esto:
http://www.adafruit.com/blog/2012/07/16/arduino-backpack-board-for-rgb-matrix-panel/
lo podés conectar en cascada y tener el tamaño que quieras.

Lo que vos planteas es completamente viable, lo único que no haría es (si puedo evitarlo) meterme a hacer la matriz por mi cuenta, suma mucho cablerío y salvo excepciones suele ser no mucho más barato que las matrices ya hechas.

La manera más fácil que encontré es desarmando el OBD2, vas a ver que tiene soldado un módulo bluetooth como los que se usan en el arduino. Fijate que  los 2 primeros pins son serial in y serial out. (tenes que cortarle el trazo al bluetooth y usarlo por cable)

Luego tenés que fijarte que frecuenca usa, el mío anda a 38400.
