* Easy to assemble kit makes for a great learning experience. All parts are easy-to-solder through-hole, with no tiny surface mount parts. * Fully open-source design means that everything is freely available and ready to be hacked, including the circuit schematic, PCB layout, part list, and microcontroller firmware. * Piezoelectric speaker is used as the pattern input, by simply tapping in the tempo or pattern. Once the metronome learns your pattern, it starts beeping with the same piezo element. * Seven-segment displays provide feedback in the form of beats-per-minute (BPM) readings. * Custom, professionally-made PCB provides a solid base for happy tappers. All circuit connections are routed on two layers without the use of vias, reducing confusion while assembling. * A Pre-programmed Microcontroller means you don't need a specialized microcontroller programmer to get started with the Tactile Metronome. If you want to experiment with modifying the firmware, an in-circuit serial programming (ICSP) header is provided to enable easy re-programming.
