How to Use a Custom Keypad for Arduino
In this tutorial, I’ll show you how to setup a 3X4 keypad on the Arduino. First I’ll explain how the Arduino detects key presses, then I’ll show you how to find the pinout of any keypad. As a simple example, I’ll show you how to print out the key presses on the LCD.
The buttons on a keypad are arranged in rows and columns. A 3X4 keypad has 4 rows and 3 columns.
Beneath each key is a membrane switch. Each switch in a row is connected to the other switches in the row by a conductive trace underneath the pad. Each switch in a column is connected the same way – one side of the switch is connected to all of the other switches in that column by a conductive trace. Each row and column is brought out to a single pin, for a total of 7 pins on a 3X4 keypad.
Parts required:
- Arduino board
- 3X4 Keypad
- 16X2 LCD display with I2C interface
- Jumper wires
Code:
Once everything is connected, upload this code to the Arduino:Downloads
