Hello,

How can I make a function run automatically X seconds after another function has been run (with Pluto) ?

Thank you

Here is how to run `f()` again after 5 seconds. This will block:

```julia
julia> f(); sleep(5); f()
2021-04-16T10:39:55.302
2021-04-16T10:40:00.340

```

This will not block so other functions can run in the meantime:

```julia
julia> f(); @async begin
           sleep(5)
           f()
       end
