In particular, a switch statement compares the value of a variable to the values specified in case statements. Then interconnect resistors in between the push switches as shown in the diagram. Print; If you want to input a manual switch signal into a digital circuit you'll need to debounce the signal so a single press doesn't appear like multiple presses. You could simply connect the input to GND (for logical zero) or leave them open (for logical one, courtesy of the pullup resistor). This library, DebouncedSwitch V3.2 will debounce a switch connected from an Arduino digital input to GND.
