AND

AND is a two-input gate that outputs the conjunction of its inputs. That is, the output is 1 only when both inputs are 1.

The code below constructs AND from a NAND gate connected to an inverter.

and.t
notLeft -2 0
notRight 1 0
notRight 0 5

in a -3..-1 0
in b 0..2 0
out o -1..1 10

The following image shows the outputs for all possible inputs.

The J-tetromino of the upper inverter functions as an OR gate.
