Hi, I'm new to Arduino and my first project is a binary LED clock. Now I want to hock two buttons to the I/O Pins to set the time. The tutorial to buttons connects the 5V directly to the I/O Pin. Just a button in between without any resistor. Is that really safe? Won't that damage the board in the …

qq push buttons without resistors?
