Or knock a diagram up with something like MS Paint and add it here?
If it relates to your other question I would reply back to Frollard - he's a helpful guy.

Can you give us a picture of your completed circuit please? Which of the 5 or so beating heart instructables did you use? Link? Did you position the 555 timer the correct way up? If you align it so the notch is away from you, pin 1 is on the top left of the 8 pins. Simplify.... Construct a simple astable or monostable to check that your 555 timer chip works.
