How to Build a Basic Logic Circuit with Project Red Gates

Placing and Wiring Gates

Project Red gates are placed like normal blocks and connect to redstone on their input and output sides. Each gate has a colored band or marking that shows which side is the output. Place your gate, then run redstone dust, insulated wire, or bundled cable into the input face and out from the output face. Gates can be rotated by right-clicking with a wrench-like tool from the mod, so check the orientation before wiring.

Choosing the Right Gate

Start simple: an AND Gate outputs a signal only when every input is powered. An OR Gate outputs when any input is powered. A NOT Gate inverts a single input. XOR outputs when inputs differ, and XNOR when they match. NAND and NOR are the inverted versions of AND and OR. For a first build, place two levers feeding an AND Gate and a lamp on the output — the lamp lights only when both levers are on.

Expanding the Circuit

Chain gates by feeding one output into the next gate's input. Keep signal strength in mind: long runs of plain redstone dust lose strength, so use a Repeater or Buffer Gate to refresh the signal. Buffer Gates pass a signal through without changing it and are useful for isolating stages. If you need multiple outputs from one signal, split the wire with a junction rather than stacking gates, which keeps timing predictable. Test each stage with a lamp before adding the next.
