Find this and other Arduino tutorials on ArduinoGetStarted.com Follow the diagrams below to connect the keypad to an Arduino Uno, depending on whether you have a 3X4 or 4X4 keypad: How to Find the Pinout of Your Keypad If your keypad's pin layout doesn't match the ones above, you can probe the pins to figure it out Interfacing Keypad with Arduino: Our today's tutorial we will learn how to interface keypad with Arduino.In embedded devices one of the essential part is keypad and it is used to interact with embedded devices, keypad is input device which is used to give commands to other devices, from calculator to computer; input is given through keypad, in this tutorial you will know how to interface.

Components Required. Hardware: ARDUINO UNO, power supply (5v), 100uF capacitor , buttons (two pieces), 1KΩ resistor (two pieces), 4x4 Keypad Module, LED, JHD_162ALCD (16x2LCD). Software: arduino IDE (Arduino nightly). Circuit Diagram and Working Explanation. In 16x2 LCD there are 16 pins over all if there is a back light, if there is no back light there will be 14 pins Arduino digital pins 7 ,6 ,5 & 4 are dedicated for my keypad rows and arduino uno digital pins 3, 2 & 1 are dedicated for keypad coulombs. In setup function i initialized the lcd in 4-bit mode and 5×7 character display, made rows output and coulombs input So, this project is about how to display characters to LCD directly by keystrokes/pressing keypad. Keypad used in this tutorial has 4 rows and 4 columns, and an LCD 20×4. You can use another type when you practicing by your self. Parts needed to display keypad to LCD using arduino UNO. Parts needed is : 1. Arduino UNO. 2. Keypad. 3. LCD. 4 Keypad. Device Control. Keypad is a library for using matrix style keypads with the Arduino. As of version 3.0 it now supports mulitple keypresses. This library is based upon the Keypad Tutorial. It was created to promote Hardware Abstraction. It improves readability of the code by hiding the pinMode and digitalRead calls for the user
