Knock Knock, Who's There?

CSEF · 2014 Electronics & Electromagnetics

Overview

Objectives/Goals Objective: To replicate, then modify an engineering project found online using the Arduino microcontroller. Methods/Materials Materials: Arduino Microcontroller, 9v battery, 3 LEDs, Rectifier Diode, Transistor, Wire, Pushbutton, Casing, piezo sensor, a motor, a buzzer, and any tools necessary. Methods: 1. Program the Arduino 2. Set up the circuit 3. Test the circuit 4. Continual Modifications due to numerous challenges 5. Hardware Setup 6. Continual Modifications due to numerous challenges Results The end result was a device completely different from the original design, resulting in an unmotorized project providing increased security, aural and visual alarms, and a cleaner look. Conclusions/Discussion This was a far more challenging project than I ever expected, and I had to address a variety of challenges. But I am very pleased with the end result and that the modifications were successful and produced a unique and helpful device.

Summary statement
