Redstone Repeater
minecraft:repeaterThe Redstone Repeater is crafted from two redstone torches, one redstone dust, and three stone, and it restores a redstone signal to full strength after it has weakened while traveling through dust. Right-clicking cycles through four delay settings of 2, 4, 6, or 8 game ticks, and the block only transmits power in one direction, acting as a diode. When powered from the side by another repeater or comparator, a repeater locks and holds its current output, a behavior widely used to build memory cells. Repeaters generate naturally in jungle temples and ancient cities.
