Description: First, ignore the sellers numbering. There's a mistake in it. Second, know that the first and last position on the keypad terminals are not being used so my keypad numbering goes like this: X 1 2 3 4 5 6 7 X Third, Arduino pin numbers 0 and 1 are generally not used for the keypad so start with 2 - 8. The corresponding pin numbers to wire to the keypad are as follows: X 7 2 6 5 8 4 3 X The correct row and col are as follows: X C2 R1 C1 R4 C3 R3 R2 X This means when you create your code (sketch), the lines of code that designate the Arduino pins being used for the key pad are as follows: byte rowPins[ROWS] = {2, 3, 4, 5}; byte colPins[COLS] = {6, 7, 8}; Package Included: 10pcs 4x3 Matrix Keyboard Module10pcs 12 Keys 3x4 Keypad Module Matrix Membrane Array Switch Keyboard for ArduinoDescription10pcs 12 Keys 3x4 Keypad Module Matrix Membrane Array Switch Keyboard for Arduino Description: First, ignore the sellers numbering.
