Coding chalenge.
So... Spent almost two hours to put this little device to work with the keypad.
The device is a arduino micro, special one that can work as mouse /keyboard or any kind of input on most devices (pc, Android phone,...)
The objective is to make a macro keypad to:
- Fast insert text
- Play sounds in games over voice chat.
Think of it like this, you start a new html file, press one key and all the base code is inserted.
So... Why so long? Tought was the hardware, tought the keypad could be set differently that most, code mistakes...
My error was all here, masked from the debugger by a if:
char keys[ROWS][COLS] = {
{'1','2','3','4'},
{'5','6','7','8'},
{'9','10','11','12'},
{'13','14','15','16'}
};
Easy to figure right? Only saw it after reading all the code twice.

First day of vacation, on a remote village cause of covid, after months of doing nothing special I made this :D
It's a keyboard to do combinations of keys (prototype) ...
Well, I made it to play sound effects in games (on voice chat)....
Ya, having a burn out fucks your motivation. At least I did something

#arduino #led matrix
Hey guys.
So, this is my first led matrix using a 74hc595n, I did all the connections right, isolated the cathodes (-), and when I tested, I only connected one cathode (to test one row, when almost all the lights turned on, in all rows doing a chacing... So I disconnected the negative wire and it still works.
One led in the arduino blinks (L).
GND is only connected to the shift register
All the rows light up doing a colum chase when there is no negative.
I'm astowned.....
