I attempted to make a Keyboard in TinkerCad, it failed but this is the final result of my attempt within the time and limited skills I have.

Step 1: Stuff

First add 3 Seven Segment Displays, Resistors and two Push Buttons like in the image

Step 2: Code

Use

// C++ code

int a = 11;

int b = 10;

int c = 7;

int d = 8;

int e = 9;

int f = 12;

int g = 13;

int dp = 6;

int OnPush = 2;

int OnPushState = 0;

int OffPush = 1;

int OffPushState = 0;

int redPin = 5;

int bluePin = 4;

int greenPin = 3;

void setup()

{

pinMode(a, OUTPUT);

pinMode(b, OUTPUT);

pinMode(c, OUTPUT);

pinMode(d, OUTPUT);

pinMode(e, OUTPUT);

pinMode(f, OUTPUT);

pinMode(g, OUTPUT);

pinMode(dp, OUTPUT);

pinMode(OnPush, INPUT);

pinMode(OffPush, INPUT);

pinMode(redPin, OUTPUT);

pinMode(greenPin, OUTPUT);

pinMode(bluePin, OUTPUT);

OnPushState = digitalRead(OnPush);

Serial.begin(9600);

}

void setColor (int red, int green, int blue) {

red = 255 - red;

green = 255 - green;

blue = 255 - blue;

analogWrite(redPin, red);

analogWrite(greenPin, green);

analogWrite(bluePin, blue);

}

void loop(){

OnPushState = digitalRead(OnPush);

if (OnPushState == HIGH){

Serial.println(OnPushState);

setColor(255, 0, 0);

Step 3: Wiring

Attach the Arduino 13Pin to row and column 2A, add another wire bin row 2B and connect that to 11B, add another wire that connects 11C with 20C.

Do something simlair with every other Pin from 12-6.

Add 330 Resistors to the bottom Common of the Seven Segment (the middle Segment wire) and have that resistor touch the PowerRail.

Connect a Push Button with Pin2 and the other with Pin1, add a resistor connecting to Power right next to the Aurdino wires and have another resistor connecting Ground.

Step 4: Schematic for the Others

Here's a Schematic if that's your style.
