Fuhu one-hand joystick

The one-handed joystick with gravity sensor will have a joystick, an MPU6050, a WS2812B, and an OLED screen. It will use a small pepper gain antenna for gain. A power management module will be added for charging management, using a 18650 battery. , there is currently some problem with the voltage collection of the joystick. Please read the comments for specific suggestions. There is room for subsequent hardware improvement by long-pressing the button to start (use NMOS and PMOS). The screen can be a welded screen, and the joystick can be a SWITCH joystick. (You have to explore it yourself). There is room for software improvement such as allowing the controller to be recognized as a game controller by the computer, using Bluetooth or WIFI or ESP-NOW to control the car, smart home, etc. to achieve gesture control, and using Fuhu's right joystick to achieve left and right hand control, etc.
