This project is an Arduino-based alarm to monitor if the computer is working. In case the computer freezes, it will emit a warning sound signal.

The project is composed from two parts: a program which runs on the computer, and an Arduino connected in an USB port.

The computer programs sends a predefined character to the Arduino, at 1 second interval. Arduino reads from the data sent from the computer. If it doesn’t receive any character for 10 seconds, it makes a sound from a buzzer attached to pin 10.

The computer program is written in Visual Basic. It is a simple Windows Forms Application, containing a Form (Form1), a label (Label1) and a timer (Timer1).

The Timer1 Interval is set to 1000 ms.
