This is a very simple puzzle to lower the bridge at Alduins Wall.
All you need to do is rotate each pillar until it shows the Dragonborn symbol on each one.
The symbol for this is sort of like a circle with an arrow going down through the middle Esbern will tell you when you get the right icon on each pillar so you really cant go wrong :
Hope this helped and hope you enjoyed! More Skyrim content like this on the way!
