A hobbyist built three different digital counter circuits on breadboards, each driving a 7-segment LED display, to illustrate how complexity evolves across design approaches. 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.
