You’ll see these parts described as variations on \u00e2\u20ac\u01534×4 Matrix 16 Keypad Keyboard Module 16 Button\u00e2\u20ac\u009d on ebay. They’re very simple: if you press a button (say S7), the row pins (R1-4; R2 for S7) and the column pins (C1-C4; C3 for S7) are connected. So pins R2 and C3 are connected when S7 is pressed. You can use the Arduino Keypad<\/a> library to talk to these, but do remember they use up 8 I\/O pins.<\/p>\n

It’s not internally routed in Fritzing, and you likely won’t be able to use it for any kind of schematic work, but who uses Fritzing for anything other than pretty pictures?<\/p>\n","protected":false},"excerpt":{"rendered":"
