Introduction: 1 to 10 Counting Machine With Arduino Uno

# Arduino uno

# 7 segment arduino display

# breadboard

# USB cable for arduino uno

# Jumper wires

# 230 omh Resistor

Step 1: Step 1 Connection

Arduino Pin 2 to Pin 9

.Arduino Pin 3 to Pin 10

.Arduino Pin 4 to Pin 4.

Arduino Pin 5 to Pin 2.

. Arduino Pin 6 to Pin 1.

Arduino Pin 8 to Pin 7.

Arduino Pin 9 to Pin 6.

GND to Pin 3 and Pin 8 each connected with 220 ohm resistors.

Step 2: Step 2 Code

int a = 2;  //For displaying segment "a"

int b = 3;  //For displaying segment "b"
int c = 4;  //For displaying segment "c"
int d = 5;  //For displaying segment "d"
int e = 6;  //For displaying segment "e" 
int f = 8;  //For displaying segment "f"
int g = 9;  //For displaying segment "g"

void setup() {
pinMode(a, OUTPUT); //A pinMode(b, OUTPUT); //B pinMode(c, OUTPUT); //C pinMode(d, OUTPUT); //D pinMode(e, OUTPUT); //E pinMode(f, OUTPUT); //F pinMode(g, OUTPUT); //G }

void displayDigit(int digit)
{ //Conditions for displaying segment a if(digit!=1 && digit != 4) digitalWrite(a,HIGH); //Conditions for displaying segment b if(digit != 5 && digit != 6) digitalWrite(b,HIGH); //Conditions for displaying segment c if(digit !=2) digitalWrite(c,HIGH); //Conditions for displaying segment d if(digit != 1 && digit !=4 && digit !=7) digitalWrite(d,HIGH); //Conditions for displaying segment e if(digit == 2 || digit ==6 || digit == 8 || digit==0) digitalWrite(e,HIGH); //Conditions for displaying segment f if(digit != 1 && digit !=2 && digit!=3 && digit !=7) digitalWrite(f,HIGH); if (digit!=0 && digit!=1 && digit !=7) digitalWrite(g,HIGH); } void turnOff() { digitalWrite(a,LOW); digitalWrite(b,LOW); digitalWrite(c,LOW); digitalWrite(d,LOW); digitalWrite(e,LOW); digitalWrite(f,LOW); digitalWrite(g,LOW); }

void loop() { for(int i=0;i<10;i++) { displayDigit(i); delay(1000); turnOff(); } }
