Arduino Uno with LCD and Keypad
Arduino UNO-based kit provides an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It contains all of the essential components required to start programming with the Arduino Uno board.
This combo includes Arduino Uno with cable, 4×4 membrane keypad, 16×2 LCD Display, 3 types of Jumper Wires.
Arduino Uno R3 Compatible Board is a microcontroller board that is based on the ATmega328. Arduino Uno has 14 digital input or output pins(where 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It has everything needed to support the microcontroller, you need to simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
LCD1602 Parallel LCD Display provides a simple and cost-effective solution for adding a 16×2 White on RGB Liquid Crystal Display into your project. The display is 16 character by 2 line display that has a very clear and high contrast.
Matrix Keypad 4 X 4 has 16 buttons, arranged in a telephone-line 3×4 grid with a column of 4 characters (A, B, C, and D). The keys are connected into a matrix, hence only 8 microcontroller pins (4-columns and 4-rows) are required to scan the pad.

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.

Arduino Sensors Combo of 5 Kit
This is a basic combo for Arduino and Robotics starter. This set can be used for obstacle sensing cars, Ultrasonic radars, school projects i.e. automatic barrier, automatic light, etc. This combo includes an ultrasonic sensor, motion sensor, IR obstacle sensor, LDR, SG90 Servo motor.
HC-SR04-Ultrasonic Distance Measuring Sensor is a very popular sensor that is found in many applications where it requires measuring distance and detect objects.
HC-SR501 PIR Motion Detector Sensor Module is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.
IR sensor module is adaptable to the environment, with a working voltage of 3.3 V to 5 V. It has a pair of infrared transmitting and receiving tubes when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving by the tube.
Photoresistor also is known as LDR(Light Dependent Resistor) as the names imply, changes the resistance with the variation in the amount of light. This particular photoresistor has a resistance of 5-10k Ohm in light and about 500k Ohm resistance in the dark.
Micro Servo 9G is lightweight, high-quality, and lightning-fast. The servo is designed to work with almost all radio control systems. It is with excellent performance that brings you to another horizon of flight. The SG90 mini servo with accessories is perfect for R/C helicopter, plane, car, boat, and truck use.
