How do you make a remote bluetooth command pushbutton that integrates with Raspberry Pi and smartphones?
I'm looking to create a simple, small remote control with a single command pushbutton that transmits over bluetooth. I want to be able to integrate this function with a smartphone or a Raspberry Pi Zero W, similar to a remote camera shutter button that could fit into a rubber/silicon type ring/sleeve attachment to fit around a water bottle, for example. I've got very limited experience in this so any help would be greatly appreciated! I've found some similar tutorials but nothing specifically for what I'm looking for in a small envelope. Thanks!
