The first uses discrete ICs like the CD4026B decade counter, the second uses an AT28C64B EEPROM as a hardware lookup table, and the third uses an ATtiny24A microcontroller with the smallest footprint. The project highlights that complexity doesn't disappear as component count shrinks — it shifts into software and tooling infrastructure — and serves as a reminder of how much modern integrated components simplify what were once sprawling hardware designs. ## Full article daily.dev links to this article rather than hosting it.
