WebIf you're building a printed circuit board to connect to the Arduino, do the same thing - collect all of the PCB grounds together and wire that to one Arduino Ground pin. If you're using a manufactured shield, you may have to get creative about collecting your grounds. A tiny breadboard is one way. Arduino (Atmega) pins default to inputs, so they don't need to be explicitly declared as inputs with pinMode() when you're using them as inputs. Pins configured this way are said to be in a high-impedance state. Input pins make extremely small demands on the circuit that they are sampling, equivalent to a series … See more Often it is useful to steer an input pin to a known state if no input is present.
