microsoft#6795 limited digital input pins to values 0/1 for keyboard and screen reader support, but digitalReadPin still required a value above 100, so it always returned 0. The new click mapping also meant that only the top of the pin set it high, which on the small edge pins was under 10% of the pin's height. Read a digital pin as high for any value above 0, matching how the pin is displayed. Clicking a digital input pin now toggles it between 0 and 1, wherever on the pin it is clicked. To match, digital pins are exposed to assistive technology as role="switch" with aria-checked rather than as a 0-1 slider, and Space and Enter toggle them. Arrow keys still work. The toggle happens on click rather than pointerdown so that screen readers in browse mode, which activate a switch by dispatching a click, can toggle it. Analog pins remain sliders and touch pins remain buttons. Fixes microsoft#7093
