A microprocessor system project using Arduino was created in order to build an alarm system for the keyboard of a computer. The alarm system consists of blinking LEDs, sound, taking a picture of the unauthorized person, sending that image per email, login when and what that person is doing, a distraction system and also the opportunity to stop the alarm through a password.
Almost every student knows the following situation. They study in the library or in the study room and then they have to leave the study room for a few minutes to go to get a fresh coffee, refill their water bottle or to go to the bathroom. But what to do with the laptop? Leaving it unsupervised for a few minutes? What happens if someone comes and tries to use it? Also at work what happens with the computer while leaving the working place for a few minutes? Can it be that someone tries to get some information from it by trying to hack the password? Also at work sometimes you can’t even lock the computer, what to do when you have to leave the office for a short time? For these scenarios this paper will present a solution.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This project aims to develop an alarm system for computer keyboards using an Arduino microcontroller. The system aims to protect against unauthorized access by detecting keyboard activity and triggering various security measures.
- Keyboard-based security system
- Arduino microcontroller implementation
- Security measures including alarms, image capture, and email notification
- Distraction system to deter unauthorized access
- Password-based system to deactivate the alarm
Zusammenfassung der Kapitel (Chapter Summaries)
The abstract provides a brief overview of the project, highlighting the use of an Arduino microcontroller to build a keyboard alarm system. It mentions key features such as blinking LEDs, sound alerts, picture capturing, email notification, and a distraction system. The introduction outlines a common scenario where a computer is left unattended and the need for a security solution. It presents the project as a discreet system that detects keyboard activity, triggers an alarm, captures an image of the unauthorized user, and sends it to the owner's email address.
The hardware chapter details the components used from the Arduino UNO R3 Starter Kit, including the Arduino microcontroller, ultrasonic sensor, LEDs, and resistors. A diagram illustrates the circuit's layout. The software chapter discusses the project's implementation, which involves both Arduino and C# components. The Arduino part handles distance detection and reacts to it, communicating with the C# part via serial communication. The C# part takes action based on the Arduino's signal and manages the alarm, including the LEDs and sound. The Arduino part also listens for stop signals from the C# part to exit the program.
