I am trying to setup a blinking light circuit of three LED lights that is remotely controlled from up to 500 feet away and have a couple questions about how this might be accomplished.
I'm using an Arduino Nano and want to power it and the light circuit off of a 850mah 3 cell Lipo battery. Is this a common power solution and if so what kind of BEC/voltage regulation is recommended? The other important detail is for my application I am trying to remotely control the system though a receiver that is not directly plugged into the Arduino, but rather one that is about 40'' away, and so connected by a wire of some sort.
Some tutorials online suggest using the Blynk app with a Bluetooth add on to control the system with a smartphone but upon further research I learned that Type 1 Bluetooth modules, the higher end of what is available, have a maximum range of roughly 300 feet which wouldn't be enough. I heard a GSM connection but would this have a greater range (and if so, how would it be setup)? All I'm looking to control is turning on and off the blinking light circuit.
Thank you for any tailored advice and/or resources that you could direct me toward.
Take a look at LoRa is a wireless data communication technology that uses a radio modulation technique that can be generated by Semtech LoRa transceiver chips. This modulation technique allows long range communication of small amounts of data (which means a low bandwidth), high immunity to interference, while minimizing power consumption. So, it allows long distance communication with low power requirements. LoRa uses unlicensed frequencies that are available worldwide. These are the most widely used frequencies:
868 MHz for Europe
915 MHz for North America
433 MHz band for Asia
Because these bands are unlicensed, anyone can freely use them without paying or having to get a license. Check the frequencies used in your country. Boards are available that work with the Arduino Nano. They also implement it with the ESP32. I have not used it but I have heard a lot of good things about it.
Is there any infrastructure in between that you could use? For example, internet? Wires? Is it line of sight with no obstructions or are there buildings/trees/walls in between?
