Step 3: Schematic

Below is a picture of the schematic. If you want to make any modifications, see the program for details of changes already programmed in. Using the parts previously mentioned, build the circuit.

NOTE: Do not solder directly to the Atmega168 if you are not experienced. Instead, solder in the socket and then insert the Atmega168 into the socket.

If you are modifying the schematic and not using an input, be sure and solder it to ground. If you are not using an output, leave it disconnected.
<p>Thats cool. I use a cheap android phone ( $40 second hand ) with a program running on it as a thief alarm. I put it under my seat. When the bike is moved the alarm will ring a second phone, or sms it. You can set it to make an audible alarm also to repel the thief, or make it do its job silently to catch him... Its on the Play Store:</p><p>https://play.google.com/store/apps/details?id=neo.dynamic.thiefalarmb1</p>

now add gps and gsm and track your bike back :)
The guy who made <a rel="nofollow" href="http://www.instructables.com/id/How-To-End-Bike-Theft-The-Honeybike-Project/">this</a> instructable uses gps to track his bike back and shocks the thief who stole the bike with a stun gun (activated by calling a mobile phone) if they are still riding it...I'm sooo making it!<br/>
I thought about it, but as you can probably tell from the picture, the bike is probably worth less than a gps. this project is more to draw attention to someone trying to mess with your bike than actually stopping somebody from stealing it.
cool i just did this to my bike last week, i used an old boat alarm, i also hoked up a stereo and lights.
