Introduction: Mini Traffic Light Arduino
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?
What do you need are:
- Arduino uno r3
- Jumper cabel (male to male)
- Resistor (optional)
- LED (Red, Yellow, Green)
Step 2: 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
Program in Arduino is made using Arduino IDE. The following is a small part of program.
Step 4: Application for Android Smartphone
Applicationfor android smartphone is made using MIT App Inventor 2 by online. The application named “Traffic Light”. The following is screenshots of application.
Step 5: Additional
