Security stuff can be fun. Just made a real foot alarm with basic materials and components. Here I've used Two LED,S one of which is simulating an alarm and a momentary switch as the pressure switch underneath a Matt. You can adapt the power supply to your needs along with resistance etc.
I'm looking for any other ideas out there to keep things simple. Please bear in mind I'm still learning and having fun whilst doing real builds and circuits in the real world. Have fun and enjoy
