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

If your keypad is different, take note of the.
- Similarly, in Arduino Password Security Lock System, if the user press # it will ask for the code. Now, if the entered code is incorrect then it will get back to standby mode. and if it is correct it will ask the user to enter the new password and confirm the password by retyping it.Here, the Arduino will compare the code, if it is incorrect then again it will get back to standby mode
