Why? This demonstrates how simple logic gates are connected and also affords a look into the node editor with a working example that can drive a single LED (basic model included).

It's also a demonstration of node groups since the more complex gates are defined by simpler ones. This is simpler than studying complex, esoteric node setups.

The output of any gate can be connected to the "input" of the LED which lights up when fed with a logic 1.

Includes the following functions/groups:

NOT (invert) -> inverts the logic level fed into it.

LOGIC -> outputs a 0 or a 1.

AND -> outputs 1 when both inputs are set to 1, 0 otherwise. Also includes the NAND function.

OR -> outputs 1 when any of its four inputs are 1 (includes logical AND, this is not a bug). Includes NOR.

XOR -> outputs 1 when EITHER of its inputs are 1 or 0 otherwise. Excludes AND. Functionally also outputs the OR, NOR and XNOR functions.

Schmitt Trigger. Outputs a hard 1 when the input level exceeds a set amount or 0 otherwise.

It's not possible to build flip-flop circuits or anything where a loop would normally be used - this is a Cycles limitation.
