I recently had the Idea to build a lottle "device" that can send/recive a signal and turn on a little LED.
This signal has to travel about 500km, and because I don't have much knowledge aboit arduino when it comes to network/intermet comunication I have 3 questions about this.
- Is this even possible with arduino?
- What is the "best/easiest" way to do it?
3What parts would I need?
Thanks already for your answers.
Have a great day.!
