Push-button (Momentary Switch): Connected to a digital input pin. 3. Resistor (likely 10kΩ): Used as a pull-down resistor to keep the input LOW when the button is not pressed. 4. Wires: • Red wire ...

Supports push buttons and toggle switches Reports # of clicks and length (in millis) of the last click Allows to define internal pull-ups Isolation between buttons Create modular code using callbacks ...

[Ed] was tasked with adding push-button degaussing ... to use an SSR to switch the coil, and after making lots of transistor-based designs on paper, grabbed a nearby Arduino.
