Tiny LED Time Watch
David Johnson-Davies designed a minimalist ATtiny85-based watch using 12 LEDs, arranged like a clock face, to show the time in analogue-style. He writes: To show the time you press the button on the watch face, and the time is then displayed for four seconds. It lights one LED to...
