Just a bit of fun and a good example of a 555 timer to turn off the buzzer after a few seconds.

Tutorial guide for when you have the board with you.
Ensure the thinner brass stick is plugged onto the lead. Turn the board on by ensuring the silver toggle switch is in the up position. Place the brass stick into the slot at the bottom middle of the board. Now slide it out and go round the circuit without touching the sides. If you do touch it, you will hear a bleep. The idea is to get all the way round without the bleep sound.
When you have done this, you can try again with the thicker brass stick which is more difficult.
