For this project you will need to create an Arduino based security system.

• It must integrate the following parts:

• An Arduino controller

• An ultrasonic sensor that detects the distance of something.

  • Ultrasonic sensor tutorial

• A piezo buzzer that goes off in response to an environmental input.

  • Piezo Buzzer Melody Command

• A relay that activates a Motor attached to a 9V battery when certain conditions are met.

  • Relay Tutorial

• Advanced Only - An infrared remote/sensor combo that activates or somehow controls the device.

  • IR Control Tutorial

• Any other sensors that make sense for this project.

Security System Parameters

The security system should:

• Be activated with a pushbutton.

• Sense when an object is coming close and start beeping at one frequency every second.

• A pushbutton should be able to disable the system.

• After 10 to 20 seconds the beeping should become constant and maybe be accompanied by some led lights.

• The LCD screen should display the status of the system throughout.
