COMPARATOR CLOCK

A comparator in subtract mode creates a decrementing signal loop. The signal decreases by the side input each cycle, wrapping around for a repeating pattern.

When to Use

Analog signal patterns, musical note block sequences, complex timing patterns.

Materials

  • ▸1 Redstone Comparator
  • ▸Redstone Dust
  • ▸1 Redstone Repeater
  • ▸Solid blocks

How to Build

  1. 1Place a comparator in subtract mode (front torch lit).
  2. 2Loop the output back to the side input using dust and a repeater.
  3. 3Provide an initial signal to the back input.
  4. 4The comparator subtracts the looped signal, creating a stepping pattern.
  5. 5Adjust the repeater delay and initial signal to change the pattern.

Variants

  • ▸Fading comparator clock (signal strength decreases each tick)
  • ▸Ring counter (multiple comparators in a loop)
  • ▸Analog wave generator (produces sawtooth or triangle waves)
