Piano HAT is inspired by Zachary Igielman's PiPiano and made with his blessing. We've taken his fabulous idea for a dinky piano add-on for the Raspberry Pi, made it touch-sensitive and added barrels of our trademark Pimoroni polish. Piano HAT is compatible with Raspberry Pi 2, B+ and A+ and comes fully assembled, with a trove of examples to get you started. 16 touch sensitive buttons - Each button on Piano HAT can be individually watched in Python and hooked up to whatever mad-cap contraption or project you can imagine. Tickle-the-ivories and create a symphony of servos or a concerto of... motors. Octave up/octave down buttons - Expand your playing horizons with two dedicated buttons you can use to shift up or down an octave, or - you know- raise and lower the drawbridge to your fortress. Instrument Cycle Button - Synth heads will be pleased to hear that it's totally possible to make this button send a patch change event to synths like Yoshimi.  All you need is a little Python glue! 16 LEDs - Ever seen on one of those learn-to-play keyboards with light-up keys? Take command of the LEDs and walk yourself through your favorite tunes, or use them as a visual metronome. Such sounds, very wow - Use with a variety of synths, both hardware and software, play .wav samples with PyGame, or create your own Piano-controlled contraptions. We've included a MIDI example which lets you play music with Sunvox, Yoshimi and others, plus a PyGame example that includes a few octaves of glorious piano and some drums for good measure. Hey Pros! - Using Python you can make Piano HAT output regular MIDI commands via a USB to MIDI adapter and take control of your hardware synth gear.
