what I want is to send the signal from rear side of the observer to 5 vertically stacked pistons to push a grown oak tree's logs.
I added a sketch of scene.
may you please help me?
my aim is to understand how is it working so I can teach my boy (8 years old)
I tried lots of things but I failed.
If possible, It's better for us if the solution uses only red stone dust and red stone torches because of simplicity.
regards, thanks.
