Game Controller Project

Below is my sketch for how I want my controller box to look like as of now. A cool idea that I had was to make buttons out of some blank plastic dice that I have left over from a board game kit. I could paint these dice to customize them for my controller. It shouldn't be too hard making them into buttons. The game that I am making my controller for is Jump King. Jump King is a really difficult game that is all about jumping up to the top of the world. To control the game with my controller I am going to do one button for left, one for right, and one button for jumping.

Schematic:

Code:

{

#include <Keyboard.h>

#include <Adafruit_CircuitPlayground.h>

#include <Adafruit_Circuit_Playground.h>

const int debounce = 100;

const int threshold = 500;

void setup()

    {

CircuitPlayground.begin();

pinMode(CPlay_SLIDESWITCHPIN, INPUT_PULLUP);

pinMode(CPLAY_LEFTBUTTON, INPUT_PULLDOWN);

pinMode(CPLAY_RIGHTBUTTON, INPUT_PULLDOWN);

Keyboard.begin();

    }

void loop()

    {

if(digitalRead(CPLAY_LEFTBUTTON))

{

Keyboard.write('A');

delay(debounce);

}

if(digitalRead(CPLAY_RIGHTBUTTON))

{

Keyboard.write('D');

delay(debounce);

}

if(CircuitPlayground.readCap(A3) > threshold && digitalRead(CPLAY_SLIDESWITCHPIN))

{

Keyboard.write(' ');

delay(debounce);

}

Serial.print(CircuitPlayground.readCap(A3));

Serial.print("\t");

Serial.println(analogRead(A2));

}

Questions:
1: How would you implement a mechanic like charge jumping into a controller like this?

2: What do you think of the box design with the dice buttons? Is it creative enough or should I go with another idea?
