Hello
Im trying to make a little gadget here.
it will use atleast 3 buttons.
1 for selecting a program (program 1-6)
2 and 3 will do some keystrokes
how can i make the 2 and 3 button to do different keystrokes depending on wich program i selected with button 1?
as i understand i need to use switch-case.
i got it to work to change program.
but when i try to add a button action in a case i get stuck.
i will later on use a small oled-screen. but for now i just trying to get it to work with the serial monitor.
this is how far got now
its a mix from 2 other examples.
Can someone please help me why i get stuck in "action1()"
I can not change program. just print Executing #1 with my button.
