Scaffolding Review

 For my project I will be trying to make a game controller for Pokemon Fire Red via an emulator on the computer. My controller idea was to be a wearable watch with face buttons for movement and for the A & B button. However, I will add an accelerometer so it can detect vigorous motion and accept that as an input for the A button. The idea for the watch came from the DS Pokemon games where the main character can wear a watch to use apps on, this will help increase immersion for the player, alongside the motion detection function for the A button, since the A button is used to choose attacks and throw Pokeballs. I have ordered all my supplies and I'm waiting for them to come in, I've begun making my (pseudo) code and schematics, I'm still having issues with making schematics so I might have to refine mine a bit further. 

Questions:
What could I do to improve the schematic of the controller?

Is there any way to simplify and streamline the controller even further?

//Libraries

#include <Adafruit_CircuitPlayground.h>

#include <Adafruit_Circuit_Playground.h>

//Variables

//Debounce button press

const int debounce = 100;

//Threshold 

const int threshold = 500;

void setup() {

  // put your setup code here, to run once:

  CircuitPlayground.begin();

  //possible bluetooth code

  //CPE accelerometer code

  //set movement range

  //read ranges

  //movement = A press

  

  

}

void loop() {

  // put your main code here, to run repeatedly:

   

      }

    }

}
