HW-834 8 Pin 16 Push Button 4X4 Matrix Keypad

This HW-834 8 pin 16 Push button 4X4 matrix keypad is a common type of membrane keypad that is use in a variety of electronics projects. It has 16 buttons arranged in a 4X4 grid. The keypad has a standard telephone keypad layout, making it easy to use for anyone.

The Push Button Keypad Module HW-834 works by using a matrix of rows and columns. When a button is press, it connects one of the rows to one of the columns, which allows the microcontroller to identify which button has pressed. The keypad has 8 pins, which are use to connect the rows and columns to the microcontroller.

The Push Button Keypad Module HW-834 can easily interface with a variety of microcontrollers, including the Arduino. To do this, you will need to connect the keypad’s 8 pins to the microcontroller’s digital pins. Once the keypad connected, you can use the microcontroller’s built-in keypad library to read the state of the buttons.

The 4X4 Matrix Keypad for MCU Or Arduino is a basic 16 button keypad for user input. The buttons are setup in a matrix format. This allows a microcontroller to ‘scan’ the 8 output pins to see which of the 16 buttons is press.

The 4X4 Matrix Keypad Module usually uses as input module in a project. It has 16 keys in total, which means the same input values. The keys of each row and column are connect through the pins outside – pin Y1-Y4 as label beside control the rows, when X1-X4, the columns.

16 Button Keypad is a matrix non- encoded keypad consisting of 16 keys in parallel. Each keypad is a combination of row and column circuits. 

Features : –

The Arduino detects which button is pressed by detecting the row and column pin that’s connected to the button. Push Button Keypad Module are most widely use in numerous mini project which requires the user or the operator to give command to the system or to feed in some data. It has general 0.1 inch male jumpers, you can easily use it in your microcontroller projects like Arduino with breadboards. Here are some of the features of the HW-834 8 pin 16 button 4×4 keypad:

• 16 buttons arranged in a 4×4 grid
