TRAFFIC SIGNAL MODEL

 Traffic signal lights control

by Arduino

 

We are making here the model of a traffic light system. As we know it works with the indication of colors like Red to stop , Yellow to wait and Green to go. Lets see how we can make it ;)

We can use this one for the making of our projects.

Needed Parts –

1-Arduino uno.  1pc

2-Red LED -   4pcs

3-Green Led – 4pc

4-Yelow LED – 4pcs

5- Resistance (100 ohm) – 12 pcs

6-Bead board (optional)

7-Arduino IDE on your PC

8- Programming cable.

Please connect all components as per given circuit Diagram.

Program => int Lane1[] = {13,12,11}; // Lane 1 Red, Yellow and Green
int Lane2[] = {10,9,8};// Lane 2 Red, Yellow and Green
int Lane3[] = {7,6,5};// Lane 3 Red, Yellow and Green
int Lane4[] = {4,3,2};// Lane 4 Red, Yellow and Green
void setup()
{
for (int i = 0; i < 3; i++)
{
pinMode(Lane1[i], OUTPUT);
pinMode(Lane2[i], OUTPUT);
pinMode(Lane3[i], OUTPUT);
pinMode(Lane4[i], OUTPUT);
}
for (int i = 0; i < 3; i++)
{
digitalWrite(Lane1[i], LOW);
digitalWrite(Lane2[i], LOW);
digitalWrite(Lane3[i], LOW);
digitalWrite(Lane4[i], LOW);
}
}
void loop()
{
digitalWrite(Lane1[2], HIGH);
digitalWrite(Lane3[0], HIGH);
digitalWrite(Lane4[0], HIGH);
digitalWrite(Lane2[0], HIGH);

}

 After connection now you can copy the given code on new file of arduino and download it on 

Arduino board.You can give 9 volt to 12 volt on Arduino IN to power up it..
