Most modern GPIO lines are implemented as a tri-state buffer. This means that the GPIO line can effectively assume three values: logical 0 (connection to ground), logical 1 (connection to VCC), and High-impedance (also called ‘floating’, ‘Hi-Z’, ‘tri-stated’).

Other types of metaphors (concept metaphors and system metaphors to some degree) seem to complement the design-pattern approach to software development. Design patterns excel in capturing solutions to recurring software problems, but they haven’t been able to capture the patterns of thinking that experts use. Metaphors and analogies offer a unique view into experts’ minds and convey the particular way the experts see and understand the problem.Miro SamekPatterns of Thinking: Metaphors in Programming
