Each half-nibble stage of the 8-bit counter occupies a full breadboard with ten 555s; the whole 40-chip string actually works and looks pretty cool doing it.

The two 8-bit counters can count to 255 whilst the 16- bit counter can count to 65,536. We learned that the simplest timer in Atmeag8 is TIMER0 with an 8-bit resolution (0-255). Timers can run ...
