Hi everybody!
My first days of Arduino was a living hell. But that's over now 
But I wan' t to share my first project, because i've searched for a lot of examples for this and couldn't find anything.
Creating a keypad on the ARLcd touchscreen
(it just sends a digital out for now to relais and maglock).
The code could probably use some cleaning up (just finished). A lot of thing could have been simpler.
But it works :).
Hope somebody can enjoy this without the 2 days of misery it cost me.
Next step. Connecting the Arduino to escaperoom controller software. (hoping I get it done in a week)
