What you need
For this first circuit, in Java or Bedrock, switch to Creative mode so you have everything at hand:
- a lever;
- redstone dust;
- a redstone lamp;
- a few solid blocks, stone for example.
The exercise shows how a signal travels. It doesn't depend on any edition-specific mechanism.
Building the circuit step by step
- Place a row of five solid blocks on the ground, in a straight line.
- Put the lever on the first block.
- Lay redstone dust on the next three blocks: it forms a continuous wire.
- Place the redstone lamp on the last block, right at the end of the wire.
- Flip the lever.
What you should see
With the lever on, the redstone wire lights up and the lamp turns on. Switch the lever off: the wire darkens and the lamp goes out. To really understand continuity, break one piece of the wire: the lamp stays off. Put it back, and everything works again.
If the lamp stays off
- Move the lamp so it directly touches the end of the wire.
- Check every joint: two pieces of dust next to each other aren't always connected.
- Stay in a straight line, with no slopes or crossings, for this first test.
Going a bit further
A redstone signal travels up to 15 blocks of wire (Redstone Dust, Minecraft Wiki). Beyond that, a repeater can extend and delay the signal, but there's no point adding one before you understand this short circuit. Little by little, you'll be able to swap the lamp for a door or a piston. Careful: some advanced builds, pistons in particular, behave differently between Java and Bedrock. Pick tutorials that state their edition.
