Begin by building your circuit. Attach the Bits in the following order: power + pressure sensor + wire + vibration motor + pulse + RGB LED + bright LED + bargraph
The most important part of this project is properly setting up your pressure sensor. Position the pressure sensor in a place where your friend is likely to put their books down (which will trigger the prank). Then, using a soft material make a small bump and attach it to the top of the pressure sensor (this will make it more sensitive). Once everything is in position tape it down securely.
Build the rest of your circuit and attach it somewhere inside the locker. We suggest using gluedots or tape to secure your circuit.
Attach a coin to the end of the vibration motor to make the noise even louder and more surprising. You can remove the small circular paper on the vibration motor and stick the coin directly to that, or use some tape to secure the coin.
Camouflage your circuit! Hide your alarm behind other books, paper, etc. Make sure not to completely cover it up.
Wait and watch as your friends jump in surprise when their locker comes to life!
