Raspberry Pi 3 Alarm System

What is this mess, you might ask?

Well this is the final prototype for my Raspberry Pi 3 Alarm system. It uses the USB keypad in the upper left corner to input the correct code, the entry and exit delay beeper is in the lower left of the photo beside the keyboard, and the LED's showing what is going on is on the breadboard just above the keyboard. You cannot see the PIR sensors, that I have mounted on the pole of the shelf that is visible in the upper right of the picture.

The next step (today) is to mount all of the components on a board and see how everything will fit into the case!

I'll post a final pic once I have everything mounted in the case.

Thanks for viewing!


  1. What is the blue board on the beardboard just above the 7 - 8 keys?

    1. Hi Randy!
      That is an RFID board. I was going to incorporate that into the alarm system so that you could arm and disarm with a RFID card or fob, but I won't have time to complete that part of the project before the festival. That'll be for Revision B when I also want to add a display to the alarm system so that you can read what state it is in. It is displaying properly on the HDMI output to a regular monitor, but I don't have enough displays for the 3 alarms that I need to build within the next 2 weeks. Got to leave something to improve upon for next year!!!
