Transmitter (usb power source) to receiver in a separate building

Using Arduino Project Guidance
1

Hello,

This is my first post here and I have no idea where to begin with this project. Was hoping some veterans could set me on the right path for the project below:

  1. A Transmitter is plugged into a usb port in my car.
  2. When the car turns on, power will be supplied to the transmitter through the usb.
  3. The transmitter will send a signal to the receiver.
  4. The receiver is located inside my house, roughly 50 feet away.
  5. The receiver will blink an LED, letting me know the power is on in the vehicle.

I'm brand new to arduino and would appreciate any direction you have as to how to make this happen. As of now I'm not quite sure which questions to even google or what to study.

Thank you.

Look at different transmitter/reciver technology to find one that fits Your needs.

Any controller would do but selecting a receiver that has the same logic level on the signals as the receiver makes things easier. There are 3.3 volt and 5 volt technologies.

RF will not penetrate the metal car body, it WILL penetrate the window glass, so make sure the transmitter is positioned so it will "shine" through the windows.

if the area where the car is has WiFi coverage you could use an ESP32 or ESP8266 both have onboard WiFi
if not consider LoRa or a HC-12

Another thing to consider is: how will your receiver know it is your particular transmitter that is sending?
