TRAFFIC LIGHT USING ARDUINO

HOW DOES IT WORK?

Basically, LED s are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The lifespan of an LED surpasses the short life of an incandescent bulb by thousands of hours. Tiny LED s are already replacing the tubes that light up LCD HDTV s to make dramatically thinner televisions.

CONNECT ACCORDINGLY AS SHOWN IN THE FIGURE

*THINGS REQUIERD

1.Arduino Uno (The brain)

2.3 LED (Red/Yellow/Green)

3.BreadBoard

4.Header Pin *Optional (By using Header Pin we can make any projects using Male to Female Jumper Wire) >Jumper Wire (Male to Female)

5.Glue Gun Using Header Pin

STEPS TO MAKE THIS PROJECT

Step 1: Place the Header Pin into the pins of Arduino After it glueing it will look like this.

Step 2:Using Glue Gun, Glue the header pin to Arduino so that it does'nt become loose.
