A Redstone Torch is a component in the game Minecraft that acts as a power source for Redstone circuits. It emits a constant redstone signal, which can be used to activate various devices like doors, pistons, and lights. Players can place it on the side of blocks or on the ground, and it can be turned off by applying a redstone signal to it. In addition to powering devices, a Redstone Torch can also be used in more complex mechanisms. It can be combined with other redstone components, such as Redstone Repeaters and Redstone Comparators, to create intricate contraptions and automated systems within the game.
