I want to develop a prototype that will measure the angle of the wearer's upper arm. As it will be strapped to their arm, the smaller and lighter, the better (it cannot interfere or effect their normal arm movement). All it has to do is beep (speaker) and/or vibrate (vibrating thingy?) in certain angle ranges plus send data to a phone app via wi-fi or Bluetooth. Pi Pico 2 or Zero-W?
I assume it can run on batteries? Or can it charge up like a Phone? I'm guessing it won't use much power to create a quiet beep or short vibration?
It's likely to be used on and off for about 30min - 2hrs.
Once again, thanks in advance for any advice, this Forum has some great people on it!
