How to Build Logic and Counting Circuits

Logic Blocks

Place a Logic block and power it. The Logic block evaluates redstone inputs and produces an output based on its configured operation. Feed it signals from Redstone Receivers, Sensors, or Wire, and take its output to whatever it controls. Use it to combine conditions — for example, only open a door when two separate inputs are both active.

Counters and Digits

Place a Counter to count incoming redstone pulses. Each pulse increments the counter; it outputs a signal when it reaches its configured threshold. A Counter Plus Screen Module or Counter Screen Module on a Screen displays the current count so you can read it without probing the block. A Digit block displays a single numeric digit and pairs with counters for readable numeric output.

Sequencing and Timing

Use a Sequencer to step through a series of outputs in order, one step per incoming pulse. Use a Timer to emit repeating pulses at a set interval. Combine Timer into Counter to count timed events, or Timer into Sequencer to advance a sequence automatically. An Analog block outputs a variable signal strength rather than on/off, which lets you feed graded values into Logic or a Screen. Wire everything together and verify each stage with a Redstone Screen Module before connecting the final output.
