Questions and Answers

The keypad uses a matrix connection of 4 rows and 3 columns. When a key is pressed, it connects one row to one column. Microcontrollers scan the matrix by activating rows and checking for a signal on columns (or vice versa) to detect which key was pressed.
You need 7 digital I/O pins (4 for rows + 3 for columns) to interface it directly with a microcontroller like Arduino, ESP32, or STM32.
-
