Eye Blink Sensor Project Kit
The Eye-Blink sensor works by illuminating the eye and eyelid area with infrared light, then monitoring the changes in the reflected light using a phototransistor and differentiator circuit.
This includes Arduino Nano, Eye Blink sensor, Buzzer, Battery, Clip Connector, and Switch.
Eye Blink sensor senses the eyeblink using infrared. The Variation Across the eye will vary as per eye blink. If the eye is closed the output is high otherwise the output is low.
Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) or ATmega168 (Arduino Nano 2.x). It has more or less the same functionality as the Arduino Duemilanove but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.
A Standard Active Buzzer Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. This PCB Mounted Active Buzzer Module can produce a range of sound tones depending on the input frequency, i.e it can generate tones between 1.5 to 2.5 kHz by switching it on and off at different frequencies either using delays or PWM.
This is a general 9v Battery for all your project and application needs.
A clip Connector is used to connect a 9V battery to the application. This snap power cable to DC 9V clip male line battery adapter for mostly used to power Arduino boards.
Rocker switch is Rocker Switch SPST ON/OFF Microswitch.
