Logic Gates
Controlling electricity gives us the ability to make yes and no decisions or true
and false
. By combining two signals, we can give a single true
or false
answer, depending on the logic
. The flow of electricity is controlled using gates
(no, not named after Bill Gates - like a gate).
The two "universal" gates are NOR
and NAND
- it is said that you can create all the other logic gates with a combination of just these two.
There are tons of videos available about logic gates. If I had to pick a favourite, my current is this one, although she talks incredibly fast and you might need to slow it down or rewind.
