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.

3.5-5.5V Standard Active Buzzer Module For Arduino
A Standard Active Alarm 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.An active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.This module is ideally suited to adding noise to your project and is compatible with a pin pitch of 2.54mm while functioning with microcontrollers such as the Arduino. This module lets you respond to programmatic changes with a lovely annoying buzzer that can be altered over a range of frequencies to ensure maximum irritation. To operate the I/O pin must receive a square wave to trigger the buzzer. This can be produced within all popular microcontrollers.Specification:- Working voltage: 3.5-5.5V
- Working current: <25mA
- PCB Dimension: 1.85 x 1.5 cm (L x W)
Feature:
- An active buzzer with a concussion internal source- so long as it will be called an energized
- The program easy to control- SCM can let a high-low sound- while passive buzzer did not.
- The Transistor drive module uses 8550
- With fixed bolt hole- easy installation- 2.6mm aperture.
