Logic Gates

​
Yisroel Newmark
A logic gate accepts a number of binary inputs (usually two), and outputs another binary value. You can connect outputs to inputs to make new logic gates. A gate with which you can make any other gate is called a universal gate. One example is the nand gate which takes these two inputs,
⁠
and
⁠
and outputs
true
⁠
⁠
One thing you can make with these components is an adder, which accepts two inputs and a carry bit (binary digit), and outputs a value and another carry bit, allowing you to chain them together. You can fidddle around with it here.
