Working Lego Pulley Mechanism

This tutorial shows you how to make a lego pulley.

I used lego WeDo 2.0 but you can use Mindstorms or any other type of mechanical legos.

Please tell me any recommendations you may have, such as making the instructions more clear.

This is to fasten the wire if you are using a mechanical part like Lego WeDo.

How to put it together.

If you pull the lever down, there is more tension. If you pull the lever up, there is less.
