I figured out a way to cheaply start my car using a text message. I wanted to be able to do this because my office is quite the distance from where I park, and my current remote starter has a range of only 20 feet or so. Learn how to do this yourself by click the link below or watching my video tutorial.
Extend the range of my vehicle’s auto-start using the cheapest solution I can think of. I would also like to keep vehicle modifications to a minimum (or none).
Trigger the auto-start remote using an Arduino connected to a cell service. User will send an SMS message to the device, which will validate the message then trigger a relay which will cause the remote to send a signal and the car will start. The device will be left in the car and run off the vehicle’s battery.
If you follow the tutorial, basic computer and electronics skills. I am assuming you can make connections using a bread board or soldering iron. I am also assuming your car already has a remote starter installed, and that you are willing to sacrifice one of the remotes.
- Arduino Uno $10
- Relay Module $5
- GPRS Shield $10
- SIM Card: Ting or T-Mobile
- Breadboard & Wires (or solder)
- Car Start Remote Control
This tutorial assumes you already have remote start on your car
SIM & Service: $10 SIM Card + $6 monthly
