Hi all, I have a project I'm working on which ended up not working as expected. So I hacked my car's spare key fob for remote starting. I'm using an UNO with a BT serial module. I wrote a simple arduino code to mimic the button presses, all controlled with an Android app.
So.. Everything's working, I can start my car with my phone but the range of the BT module is nowhere near enough to make it practical.
So I'd like to add a clock to my circuit and have it in the car so when the designated time arrives, it will call the function to start the car. Would this be possible without a RTC? I was thinking, instead of starting the car with the app, I can pair with the module, set the time to start the car, save that data into eeprom and have it setup like that. Any thoughts?
