A comment on Ask HN: Why is binary used instead of ternary?.

If you think in terms of voltage on a pin, how you would implement ternary? Binary is simple: 0V, or 5V (at least a long time ago...). Transitioning from one state to the other is obvious. How would you do it with ternary logic?

You could have predefined gates 0V-1V= 0 1V-2V= 1 2V-3V= 2 / -1

Do negative voltages exist?

Positive voltage, negative voltage, no voltage

Ternary allows for measurements of relativity at the pin level whereas binary is a yes/no...

Well there are so many options here, which make things that much more exciting. So basically: 0V, 5V, everything else
