Bike/e-scooter Anti-Theft Alarm

Projects General Guidance
1

I am building a anti-theft alarm for my e-scooter. This will be my first real project so I don't know a lot of what I am doing. But I'm sure I will learn it along the way.

This is how I imagine my device (all is in my amazon cart)

  • Enclosed in IP65 case.
  • Arduino Uno (I have weaker ones too and Teensy)
  • Loud speaker for alarm. Will be outside i have 6 of them. Never outside light rain more than 10 min
  • Bluetooth to control the device
  • GPS to track if stolen
  • Accelerometer to activate alarm on movement
  • GPRS-GSM module to upload or SMS my GPS coords
  • External antenna w MHF connector for the GSM+GPS. Dunno about BT
  • Some way to power on/off (not yet figured out)

Added everything in quick into circuito.io. Don't mind the wiring, that's a later problem.

What more do I need?
Or let's put it this way, is it just too hook everything up as in the circuito.io?

The lipo I am assuming is for debug, I think you need to investigate the electrical system regarding transients such as load dump, reverse battery etc. A schematic not that frizzy thing would be much better.

I thought about driving it with 4x3,7v lipos in serial. Please help me if that is a bad idea! I am buying some stepper down LM2596S just in case for this or future project if that can be useful?

I am really bad at electricity. My dad is an Electrician and still hasn't been able to teach me ohms law. It's like my dyslexia :frowning:
