Use this components to build the project:
    Ultasonic Sensor: Determine how close the car/object is to the gate. 
    Pressure Sensor: Determine whether is it a car or other object.
    Servo Motor: To open and close the garage gate.
    LCD: To display the number of spot left in the garage.
    RGB LED: To represent the red-green light 

NEEDED PARTS:
    -SERVO MOTOR https://www.amazon.com/Micro-Servos-Helicopter-Airplane-Controls/dp/B07MLR1498/ref=sr_1_6?dchild=1&keywords=servo+motor&qid=1614047170&s=toys-and-games&sr=1-6
    -RGB LIGHT https://www.amazon.com/ELEGOO-Diffused-Assorted-Flashing-Arduino/dp/B0739VKXYG/ref=sr_1_3?dchild=1&keywords=rgb+arduino&qid=1614047226&sr=8-3
    -PIEZO SPEAKER https://www.amazon.com/mxuteuk-Electronic-Computers-Printers-Components/dp/B07VK1GJ9X/ref=sr_1_4?crid=3CIE4AXXLHG37&dchild=1&keywords=piezo+speaker&qid=1614047495&sprefix=piezo+spea%2Caps%2C183&sr=8-4
    -9V BATTERY https://www.amazon.com/AmazonBasics-Everyday-Alkaline-Batteries-8-Pack/dp/B0774D64LT/ref=sr_1_5?crid=YNWSMFV1I6BK&dchild=1&keywords=9%2Bvolt%2Bbattery&qid=1614047528&sprefix=9%2Bv%2Caps%2C227&sr=8-5&th=1
    -PRESSURE SENSOR https://www.amazon.com/Sensitive-Resistor-Pressure-Diameter-Resistance-Type/dp/B07MP4RL9Q/ref=psdc_306935011_t1_B07T1CHY58
PLAN:
    -Start by changing the color of the lights(5pins total)
    -Make the piezo sound as the light go green (4pins total)
    -Make the servo motor go up when the light is green and make it go back down and proceed to turn the light back to red(5pins)
    -Make the ultrasonic sensor sense object that are close to it (7pins)
    -Mesure the pressure of the object to classify it (4pins)
    -This is a maybe (hook up the ultrasonic sensor on a servo mortor.)
    -close the gate if the pressure sensor is not detecting any pressure
    -LCD hook up (10pins)

    30pins total
