You can also right click on a repeater to slow the speed that it transmits its signal. You can use this repeating signal as many times as you want as long as the repeaters are still being powered. Redstone repeaters can be used to repeat the signal and act as a new power source as long as it is receiving power.īy placing a repeater down its track the redstone signal becomes repeated and will continue until it reaches another fifteen blocks. The top lamp is not being powered because the redstone signal peeters out before it reaches the lamp. Redstone can only emit up to fifteen blocks. A strongly powered block can power adjacent blocks. Another thing to note is that a redstone repeater powering a block will input a strong signal rather than a weak signal from redstone dust. It will transmit the signal to the block in front of it, this can be the output you want like redstone lamps, another redstone repeater, more redstone dust, etc. It will transmit signals when the back is powered with a powered redstone dust, redstone torch, redstone block and other power sources. A redstone signal will not go through the back of a repeater.Ī repeater only transmit signals one way. You may run into situations where the redstone has to come back to its input. If you want to prevent a signal from looping back into itself you can use redstone repeaters for that. In a Nutshell: There are 4 different uses for a redstone repeater: you can transmit signals further, you can delay the signal from reaching its output, they can also prevent signals from moving backwards if you need another input further up the wiring, and finally you can lock signals into a certain state.Ī redstone repeater will not accept a signal from the opposite direction that it is facing. Much of redstone is straightforward and logical, it becomes easier to understand when you see it for yourself. It helps to know some basics like a redstone pulse will only go out to fifteen blocks.
