Arduino Nano: I2C Matrix Keypad With PCF8574/PCF8574A GPIO and Visuino: Matrix Keypads are among the simplest and most popular ways to enter keyboard information into Arduino type micro-controllers. I already made an Instructable showing how you can connect Keypad to Arduino Nano. The downside is that to connect the k. . .

Adafruit Industries, Unique fun DIY electronics and kits MCP23017 - i2c 16 input/output port expander ID: 732 - Add another 16 pins to your microcontroller using a MCP23017 port expander. The MCP23017 uses two i2c pins (these can be shared with other i2c devices), and in exchange gives you 16 general purpose pins. We even have an Arduino

The example code is really straightforward. The button pins are initialized as inputs with internal pull-up resistors enabled. The USB functionality starts with TrinketKeyboard. begin();, and then the loop will poll the buttons. If the button on pin #0 is pressed, the keyboard will type out 'A' until the button is released.

/24/2013A while back I posted about using the 4x4 Universal 16 Key Keypad for Arduino. One drawback to the parallel connection is that it requires 8 digital pins for the connections. There is an alternative approach that uses an PCF8574(P) I/O expander that connects to the Arduino Uno via I2C using just 2 data lines.
