 Arduino Projects Ideas - Digital Dice (7-segment Display)

Components:
7-segment display (common cathode)
8× 220Ω resistors
Push button
Arduino UNO

Wiring:
Connect A-G segments to pins 2–8
Common cathode to GND
Button to pin 9 with pull-down resistor

Code (sample for one digit):

const byte segments[] = {2,3,4,5,6,7,8};
const byte dice[6][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
};

void setup() {
  for(int i=0; i<7; i++) pinMode(segments[i], OUTPUT);
  pinMode(9, INPUT);
}

void loop() {
  if(digitalRead(9) == HIGH){int num = random(6);for(int i=0; i<7; i++)  digitalWrite(segments[i], dice[num][i]);delay(500);
  }
}
