Thetraffic lights are very important in everyday life, especially in driving down the road. Now I will make a small traffic lights (mini traffic light) which will simulate the workings of an actual traffic light. Mini traffic light is made using a microcontroller arduino uno R3.

Step 1: • What Do You Need?

Picture of • What Do You Need?

What do you need are:

  1. Arduino uno r3
  2. Breadboard
  3. Jumper cabel (male to male)
  4. Resistor (optional)
  5. LED (Red, Yellow, Green)

Step 2: Connection

Picture of Connection

The components that already exist, then connected in order to be integrated each other. This connection is made in Fritzing software. The following is the diagram on picture.

Step 3: Program
