Button or Switch Control

-

how control button and/or switch using arduino? ideally still have manual toggle, but  1 not required. input, riley

what mean "control button or switch"?   do mean want read button arduino?  simple digitalread statement.

or mean want arduino push button?  buttons connect ground many times needed drive 1 of pins on button ground.  or use transistor or relay make contact between 2 pins on button.
