This clock was inspired by some 2.3″ one-digit 7-segment displays I saw on AliExpress [1]. I decided it would be fun to have a clock that you can see clearly from a distance. The displays come in a variety of colours and voltages; I chose the red 4V versions so I could drive them directly from the microcontroller’s I/O lines without needing driver transistors. My displays are common-cathode, but a minor change to the program would make it work with common-anode displays.
