Icon Concept (For Designer)

Ek Ludo ka Dana (Dice) hawa mein uchla hua hai. Side mein 7-Segment Display par number ‘6’ chamak raha hai.

What It Does (Yeh Kya Karta Hai?)

Bilkul asli Ludo ke daane ki tarah!

Aap Button dabayenge.
Screen par numbers tezi se badlenge (Shuffle animation).
Phir achanak ek Random Number (1 se 6) par ruk jayega. Ismein cheating ka koi chance nahi! 😉

Components Required

Microcontroller: Arduino Uno
7-Segment Display (1 Digit, 10 Pins wala)
1 Resistor (220 Ohm) – (Current control karne ke liye)
Jumper Wires (Kam se kam 8)
1 Push Button

Wiring (Taarein Jorna)

Step 1: Common Connection (Resistor Yahan Lagega)

Display ki Neeche wali line mein jo Beech wala Pin (Pin 3) hai:

Us Pin se Resistor jodein.
Resistor ka doosra sira Arduino GND mein lagayen. (Is se sab LEDs safe rahengi).

Step 2: Segments Connection (A to G)

🔻 Neeche Wali Line (Left se shuru karein):

Pehli Pin (E): → Arduino Pin 6
Dusri Pin (D): → Arduino Pin 5
Teesri (Common): → Yeh humne Resistor/GND se jod di hai.
Chothi Pin (C): → Arduino Pin 4
Paanchvi (Dot): → Khali chhor dein.

🔺 Upar Wali Line (Left se shuru karein):

Pehli Pin (G): → Arduino Pin 8
Dusri Pin (F): → Arduino Pin 7
Teesri (Common): → Khali chhor dein (Neeche wali ground kaafi hai).
Chothi Pin (A): → Arduino Pin 2
Paanchvi Pin (B): → Arduino Pin 3

Button Add Karein:

Button ki ek taang → GND (Blue Line).
Button ki doosri taang → Pin 10.

Code

// Project 19: Digital Dice (Ludo)
// PlzPapa Robotic Kit

// Display Pins
int a = 2; int b = 3; int c = 4; int d = 5; int e = 6; int f = 7; int g = 8;
int buttonPin = 10;

// Numbers (0-9 Patterns)
byte numberPatterns[10][7] = {
  {1,1,1,1,1,1,0}, // 0
  {0,1,1,0,0,0,0}, // 1
  {1,1,0,1,1,0,1}, // 2
  {1,1,1,1,0,0,1}, // 3
  {0,1,1,0,0,1,1}, // 4
  {1,0,1,1,0,1,1}, // 5
  {1,0,1,1,1,1,1}, // 6
  {1,1,1,0,0,0,0}, // 7
  {1,1,1,1,1,1,1}, // 8
  {1,1,1,1,0,1,1}  // 9
};

void setup() {
  for(int i=2; i<=8; i++) { pinMode(i, OUTPUT); }
  pinMode(buttonPin, INPUT_PULLUP);
  
  // Randomness ko behtar karne ke liye (Hawa se reading lo)
  randomSeed(analogRead(0));
  
  // Shuru mein '-' (Dash) dikhao (Beech wali line ON)
  digitalWrite(g, HIGH); 
}

void loop() {
  // Agar Button dabaya
  if (digitalRead(buttonPin) == LOW) {
    
    // --- ANIMATION (Shuffle Effect) ---
    // Numbers ko tezi se ghumao taake lage dice hil raha hai
    for (int i=0; i<15; i++) {
      int fakeRoll = random(1, 7); // 1 se 6 koi bhi number
      displayNumber(fakeRoll);
      delay(50); // Bohot tez change karo
    }
    
    // --- FINAL RESULT ---
    int finalNumber = random(1, 7); // Asli number chuno (1 se 6)
    displayNumber(finalNumber);
    
    // Button chhodne ka intezaar karo
    while(digitalRead(buttonPin) == LOW); 
    delay(200);
  }
}

// Display Function
void displayNumber(int num) {
  // Pehle sab saaf karo (Optional but safe)
  for(int i=2; i<=8; i++) digitalWrite(i, LOW);

  int pin = 2;
  for(int i=0; i<7; i++) {
    digitalWrite(pin, numberPatterns[num][i]);
    pin++;
  }
}

Test Kaise Karein:

Code upload karein.
Shuru mein screen par sirf ek Line (-) hogi ya blank hoga.
Button Dabayen: Numbers tezi se bhagenge (Jaise slot machine).
Rukega: Ek number par ruk jayega (Jaise 4).
Dubara dabayen, shayad ab 6 aaye ya 1 aaye.
