have anyone ever build a switch button to control LED matrix?

Use a pushbutton like funkyguy says. Everytime it is pressed you add 1 to a counter, when it gets to 7 you reset to 1.

void loop(){
if (digitalRead(message_button)== 0 ){  // assumes input pin with internal pullup resistor, switched to ground
message_count = message_count +1;
if (message_count == 7){message_count = 1;}
}
switch (message_count){
case 1:
// message 1 code here
break;
case 2:
//mesage 2 code here
break;
:
:
case 6:
// message 6 code here
break;
}  // end switch
} // end void loop
