A bluetooth servo/latch system

Projects General Guidance
1

Hi!

I was looking to start a project that does the following:

  1. Device is less than 200 meters away (more than likely <150 meters), outdoors with no obstructions
  2. Using bluetooth(?) send command to move servo, kind of like a latch system
  3. Close latch

Needs to be battery powered

I'm unsure of the range and capabilities - would this be possible? If so, are there any components that I would need other than the arduino uno r3 and would anyone have recommendations?

Welcome to the forum

A question for you

Forgetting the Arduino for now, are you able to establish communication between 2 Bluetooth devices such as your 'phone and your PC at a range of 200 metres ?

Thank you!

Maybe 200m was a bit much, but realistically 100m using a HM-10 would be fine? Then use one of those BT android apps to send a simple command over - it's completely open area so I would think it's alright?

In theory maybe, in real live .. no way. WiFi will work, so ESP32 would be a good startingpoint.

Hello baardie

Welcome to the world's best Arduino forum ever.

Take a search engine of your choice and ask the WWW for 'arduino remote control' to collect some data to be sorted out to get the needed information.

Have a nice day and enjoy coding in C++.
