This project uses capacitive sensors to direct assist modern day education and security. We will be using an Arduino board that is connected to capacitive sensors. It operates at 5 volts although the input is 9 volts. The capacitive sensors are made from aluminum and a one mega-ohm to 40 mega-ohm resistor. This technology will activate (and perform a task) when a human body approaches. Therefore, we can put this technology into application. Our first demonstration will involve attaching a piece of paper to the aluminum foil. When students trace the paper using their fingers, they will activate the capacitive sensor. Thus, we can make education paper-less and ecofriendly by incorporating these devices in modern day classrooms. Also, a lot of schools nowadays plan on using light-radiating devices such as iPads in classrooms, placed right in front of the students' eyes. Research has shown that using these devices for a long period of time has many negative effects to the student's health. By using this device, schools can operate using technology that is not harmful to their body. Further, the sensors activate without direct contact (you will see on the day of the presentation), so it is completely safe and sanitary for others to use. In addition to our demonstration, we will be using 64 light emitting diodes to display signs. If we have time, we will start on our second demonstration of applying this technology to modern security systems.
