Simple Laser Security Door will not let anyone pass through it. You will need to pull the lever down if you want to cross.
In this guide, you will learn the method to make a Simple Laser Security Door. Just go through the guide and follow step-by-step instructions to make one.
The first thing you need to do is to dig a ground up to 5*3 blocks and it’s depth should be 3 blocks. Place the iron blocks in the dug ground.
And then place three beacons in the middle of these iron blocks. Cover the sides with blocks of grass as shown in the image below.
Add a dark oak fence gate at the back side of the beacons and three redstone repeaters on the front. Use redstone dust on the front side of repeaters.
The next thing you need to do is to cover the front part of the hole with white carpet and use grass blocks to fill up the sides. And then add a lever on the left side in the same way as shown in the image below.
This lever will help you to activate the fence gate. Place three blocks of iron upside down on the left side and three on the right side. Add red stained glass blocks on all three laser beams and white carpet at the top of these glass blocks.
