Arduino Bicycle Alarm and Lights

Step 4 Mount Bicycle Alarm in a Case

Once you build the circuit, it is time to mount it in the project enclosure. I used the drill to make holes for the key lock, push button switch, wires, and the buzzer. The size of each of these holes will depend on your components. Make sure to lay the components out before drilling the holes to make sure everything will fit. Be especially careful about the depth of the larger components. If you want to keep the bicycle where the alarm might get wet, some silicone caulk in all holes would help to keep water out. This alarm is not designed to be totally waterproof however. BE SURE TO PUT THE BATTERIES IN BEFORE SEALING THE BOX. This is especially important if you plan to seal the box with a rechargeable pack inside.

NOTE: I chose not to use the tamper prevention feature just yet, so there is no wire coming out for it. Should you choose to implement all of the features of this alarm, you will have 7 pairs of wires coming out of your case.

NOTE: The battery connector is in place on my alarm should I choose to ever use a rechargeable battery pack. If you never plan on using a rechargeable battery pack, you can leave it off.
