DFRobot Gravity Industrial Grade Analog pH Sensor / Meter Pro Kit V2

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.

Applications:

• Security System
• Calculator
