Project Integration
The seven connections correspond to four rows and three columns. A controller scans the matrix to identify the pressed key; use a compatible keypad library or your own scanning routine.
Confirm the row and column pin order before wiring. Suitable projects include Arduino input panels, Raspberry Pi GPIO interfaces, code-entry demonstrations and menu controls. Configure the circuit for the logic voltage of your controller.
