Code for detecting blocks

Title: Code for detecting blocks

Hello, I am new to computer craft and was wondering if there was any way I could make a program that would allow my turtle to turn right when it hit a wall but keep running afterward?

turtle.digDown() --- when there is no block in front of it
turtle.placeDown()
turtle.forward()
turtle.turnRight() --when it hits a wall

Dont know in what perspective it is used in, but here is what I came up with:

while true do -- infinite loop
  if turtle.detect() == false then
    turtle.digDown()
  end
  turtle.placeDown()
  turtle.forward()
  if turtle.detect() then
     turtle.turnRight()
  end
sleep(0) -- otherwise the loop will yield
end

I hope I helped
