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.

Basic Electronic Components, DIY Learning and Robot Kits, SensorsL298N 2A Based Motor Driver Controller Module+100RPM Dual Shaft BO Motor (4pcs)+4 x 65mm Robot Wheel-Combo
- L298N Motor Driver Controller Module is a high power motor driver for driving DC and Stepper motors. It can control upto 4 DC motors, or 2 DC motors with directional and speed control. This motor driver is for robotics and mechatronics projects. The 150 RPM Dual Shaft BO Motor is a straight motor which gives good torque and RPM at lower operating voltages. It is a geared DC Motor. It is an alternative to metal gear DC motors. The 65MM Wheel is made up of standard grade rubber.
- L298N: Current Sense for each motor | Heatsink for better performance | Power-On LED indicator | Directional control | Speed control | High power motor || BO motor: Low density and inertia | Capability to absorb shock and vibration as a result of elastic compliance | Ability to operate with minimum or no lubrication | Relatively low coefficient of friction || Wheel: Car hub is reinforced nylon | Sturdy | Tire with sponge liner for more strength | With upgraded tire tread for greater friction
- Dimensions: L298N(LxWxH):44x44x28mm | Shaft length:7mm | Shaft Diameter:5.5mm | Motor(LxWxH):55x48x23mm | Diameter of wheel:65mm | Center Shaft Hole Diameter (mm):5.4 (Round edge) and 3.5 (Flat edge)
- The L298N motor driver is perfect for robotics and mechatronics projects. It can also be used for controlling motors from microcontrollers, switches, relays, etc. It is capable of driving DC and Stepper motors for micro mouse, line following robots, robot arms, etc. The BO motor is ideal for DIY enthusiasts. This motor set is inexpensive, small, easy to install and ideally suited for use in a mobile robot car. The 65mm wheel is only compatible with BO motor.
- L298N: Input Voltage:3.2V-40V DC | L298N Dual H-Bridge DC Motor Driver | Operating voltage:DC 5V-35V | Peak Current:2Amps | Speed Control:PWM | Control Signal input voltage range:0.3V≤Vin≤1.5V (Low), 2.3≤Vin≤Vss (High) | Max. power consumption:20W (when the temperature T=75℃) || BO Motor: Operating Voltage:3 to 12V | Current (without loading):40-180mA | RPM:100 | Output Torque:0.8 kgcm | Motor Design: L-shaped || Wheel: Loading Capacity (kg):2.5 | D hole For BO Motor (mm):6

HC-05 Bluetooth Wireless UART Module
HC-05 is a Bluetooth Transceiver Module and has TTL Output. HC-05 6 Pin Wireless Serial Bluetooth Module is a Bluetooth module for use with any microcontroller. It uses the UART protocol to make it easy to send and receive data wirelessly. This Bluetooth module is a completely qualified Bluetooth V2+Enhanced Data Rate (EDR). It is 3Mbps Module with 2.4GHz radio transceiver and baseband. It has CSR Bluecore 04, an external single-chip Bluetooth system with CMOS technology and AFH, Adaptive Frequency Hopping, feature.
The HC-06 module is a slave only device. This means that it can connect to most phones and computers with Bluetooth but it cannot connect to another slave-only device such as keyboards and other HC-06 modules. To connect with other slave devices a master module would be necessary such as the HC-05 version which can do both master and slave.
Specification and Features:
- Voltage supply: 3.5v to 5v
- Working current: matching for 30 mA, matching the communication for 8 mA.
