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.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
