How do I read the keys with an Arduino?
The keys form a row and column matrix, so the microcontroller drives the rows and reads the columns to detect a pressed key. The Keypad library for Arduino handles this scanning. Confirm the pinout against the product labeling, because a 4x5 matrix normally needs nine signal lines.
Does it need a pull-up resistor or diodes?
Column or row lines usually need pull-up or pull-down resistors, which can be set in the microcontroller's internal settings. Check the datasheet or product labeling to confirm whether the matrix includes diodes.
