My idea is a 2 digit counter that can be increased by pressing a button.

Supplies

circuitcomponents.jpg

5 - 220 ohm resistors

1 - Breadboard

1 - Push Buttons

2 - Seven Segment Displays

20 - Wires

Placing the Circuit Components

These are all of the components used in the circuit, except for the wires used to connect them.



Wiring the Circuit

This is how I wired the circuit, it is much clearer on the schematic than the physical circuit.

Color code:

a = Orange

b = Yellow

c = Green

d = Turqoise

e = Blue

f = Purple

g = Pink

Positive = Red

Negative = Black

Input = Grey

Pin Connections

7 Segment display connections:

a = 13;

b = 12;

c = 11;

d = 10;

e = 9;

f = 8;

g = 7;

a1 = A0;

b1 = A1;

c1 = A2;

d1 = A3;

e1 = A4;

f1 = A5;

g1 = 6;


I set these pins as a - g for the seven segment displays, the variables with 1s after them were for the other 7 Segment display

Then, I set pin 2 as the input pin for the button:

const int buttonPin = 2;



The Code

This is the arduino code that I used in my circuit:


const int a = 13;

const int b = 12;

const int c = 11;

const int d = 10;

const int e = 9;

const int f = 8;

const int g = 7;

const int a1 = A0;

const int b1 = A1;

const int c1 = A2;

const int d1 = A3;

const int e1 = A4;

const int f1 = A5;

const int g1 = 6;

const int buttonPin = 2;

int count = 0;

int number = 0;

int lastButtonState = 0;

void setup() {

pinMode(buttonPin, INPUT);

pinMode(a, OUTPUT);

pinMode(b, OUTPUT);

pinMode(c, OUTPUT);

pinMode(d, OUTPUT);

pinMode(e, OUTPUT);

pinMode(f, OUTPUT);

pinMode(g, OUTPUT);

pinMode(a1, OUTPUT);

pinMode(b1, OUTPUT);

pinMode(c1, OUTPUT);

pinMode(d1, OUTPUT);

pinMode(e1, OUTPUT);

pinMode(f1, OUTPUT);

pinMode(g1, OUTPUT);

}

void loop() {

number = digitalRead(buttonPin);

if (number != lastButtonState) {

if (number == HIGH) {

count++;

if (count < 0) count = 99;

}

delay(200); // debounce

}

switch(count) {
