Step 2: Cutting the Wood
After you get your materials you cut the wood to the size of your door frame (or any size you want) all you need to do this is an exacto knife and a steady hand.
Step 3: Adding Padding
After your wood is the size you want it just get some cheap foam padding, just take thin pieces and place them on the wood leaving space in between them, put them were they will be in between the two pieces of wood. Then when there were you want them to be tape them to the wood so they are secure and don't slide around.
Step 4: Adding the Aluminium Foil
Next you get tin foil and put tinfoil in the spaces between the foam and tape the in place. Make sure you add this on both pieces of wood.
Step 5: Adding Nails
Now get some nails and tape then to the aluminium foil with the dull end sticking out do this on all tin foil strips. Make sure the nail is touching the foil so it can conduce electricity.
Step 6: Alligator Clips
Now clip an alligator to every nail and clip all the other ends to each other,so all of them are connected and connected to the alarm.
Step 7: Finishing It of
Last you clip one alligator clip to the ones on the nails then clip that one to the makeymakey bored(clip it to the click button).And put it in your doorway and hook the makey makey up to the computer.

After its all hooked up go to an online alarm and hover your mouse over the test button and when someone steps on the board the tin foils will touch and complete the electric current and click the alarm on causing a sound.
