The PiPiano uses an I2C port expander to give you thirteen buttons laid out like an octave of a piano keyboard, along with three LEDs and a piezo speaker; and as you’ll see if you watch the video, if the piezo speaker isn’t enough for you, there’s more than one way to use the PiPiano to create other sounds through speakers or headphones. Of course, all the buttons, LEDs and buzzer can be used as input or output for your other projects, and thanks to the I2C expander, the board uses only three of the Raspberry Pi’s GPIO pins – there’s an option to receive one with a stacking header so that you still have access to the rest of the pins if you have other plans for those.
