Hi there,
I want to post my "14x7" Dartboard config.
The "problem" was the big matrix cause the inner single circle is different the other one.
i got the arduino mega for it, and doubles some keys.

const byte numRows = 7; //for rows
const byte numCols = 14; //for columns
const int debounceTime = 100;//20 works better than great !
//define the cymbols on the buttons of the keypads
char keymap[numRows][numCols] = {
{'0','1','2','3','4','5','6','7','8','9','*','a','b','c'},
