My Proposal and Some Basic Idea

For my final project, I do want to make a smart device that would be useful for people's daily life. My first decision was to make a smart reading and writing postures correcting reminder for those young children to prevent their eyes from being shortsighted. However, soon I found that this design might be too simple to work out since I only need to use a distance sensor as my main chip, which was not hard enough to be qualified as final. So I changed my mind and came up with another smart device. I call it Anti-Theft Smart bag.

Actually, I'm not really making a bag, what I want to make is an alarm device that is special for bag safety. We know that if someone try to steal something from your bag, your bag will be opened up and exposed to incidence of light. So my alarm device will basically focus on detecting the incidence of light. Once the alarm device catches the incident light intensity, it will raise the alarm. To realize that, I will use a photo-resistor in my circuit since photo-resistor is a light-controlled variable resistor. By photo-resistor, the alarm device would be sensitive to the light. Photo-Resistor is the key to my project but not the hard part. The hard part would be applying an infrared remote set into my project. The infrared remote set is composed of one controller and one receiver. I would use the infrared remote controller to turn on/off the alarm device. This step is really necessarily because without this step, the alarm device will automatically operate as long as it feels the light intensity. In other words, we will trigger the alarm by ourselves during we using the bag. So we need such remote kit to turn on the device when we need it to take care of our bags and turn off the device during we using our bags. Once the alarm is raised, a buzzer connected in the circuit will sounds and in the same time, an LED will blink. All these staff will be built on Arduino Uno R3 board.
