Good afternoon/morning/evening,
I have conceptualized a multifunctional button/joystick to connect to my phone via bluetooth. I have attached a CAD design of the button/joystick. It is a simple device, however I am unsure of how to begin, including what products to buy or what to do.
Some items I have been looking at are:
Bluetooth module HC-06
Microchip RN4870/71
Adafruit Trinket
Mikroe 1824
I am also unsure if I need to create my own custom PCB board to fit the particular dimensions of this button/joystick.
It is a small wearable device and
Functionalities of the button/joystick include:
Center click - (Play/ pause music/ Answer/ end phone calls
Center push 3 seconds Hold - connect bluetooth
left tilt click - (previous track )
right tilt click - (skip track)
volume knob rotation (potentiometer or Rotary clickTM?)
and an LED
Alternatively, would it be easier to have the button function using only clicks (Non-joystick)
1 click - (play/pause answer/end phone calls)
2 click (previous)
3 click (next)
hold (Connect to bluetooth)
Also, Would this option be cheaper?
I hope that was clear. Thanks in advance.
