How to make an automatic alarm system in Minecraft

Minecraft has many beautiful blocks with unique textures, used by players to create attractive structures in the game. Since the addition of Redstone, the idea of making these structures functional has become possible.

One of the simplest redstone contraptions commonly seen in a Minecraft base is the automatic alarm system. These systems are mostly built on Survival Multiplayer (SMP) servers as there are many players on the server that may try to steal resources from bases.

When a stranger on an SMP server tries to enter a house to steal resources, the alarm system will go off, alerting everyone close to the base and forcing the thief to flee from there.

This article covers the steps for building a simple automatic alarm system in Minecraft.

Step 5: Cover all of the redstone using any block.

Once the building process is finished, the players entering the house will trigger the alarm system alerting everyone in the area. The alarm can be turned off using the lever inside.
