Instructables
Picture of Arduino Automated Garage Door System
Our TEJ Class was given the challenge to build something that is either original or and improvement to something that already exists and must somehow implement "Arduino"

This Instructable will allow for you to create a garage door equipped with a sensor to sense when a car is in presence, an LED and a piezo buzzer warning system to indicate the operation of the garage door.  

For most of us the task of having to use a key to open the garage door or trying to find the car keys and or even the keyless wireless garage door remote is a task that we all don't want to do especially when we're short on time hence our innovation, a sensor activated garage door.
How it works:
When a car rolls up to the painted line located on the driveway, it will disrupt the follow of light that was originally being received by the sensor, this will then lift the garage door for 5 seconds wait for 5 seconds to allow for the car to enter the garage then lower the garage door. Now this project is cheap, effective, and able to be easily implemented in the real world.

Step 1: Materials

The materials required for the project are: 
-Wood
-Paint (For aesthetic purposes)
-Hinges (For the movement of the garage door)
-Wires (To hookup the electronics)
-Breadboard (To hold all the wires down)
-Motor (To lift motor)
-Arduino (To program the electronics)
-Half H driver (To allow for the motor to change direction)
-Resistors
