Compose a monophone microbit musical masterpiece with the :KLEF Piano for the BBC micro:bit Kit. The blending of coding and music composition makes this kit perfect for any STEM/STEAM or coding program. Students write their code using the MakeCode, MicroPython, and Mu editors. Piano features 15 capacitive touch pads, with 13 arranged as a single octave and 2 up/down function buttons that allows user to shift octaves. Versatile piano can also be used as a control surface to trigger the sending of data to another micro:bit using the micro:bit's radio module, or as a remote control for your robots. The piano also features an onboard amplifier circuit, an onboard speaker, and an onboard edge connector that the micro:bit slots into.

BBC micro:bit is a powerful handheld, fully programmable computer designed by the BBC and a number of partners to encourage students to get actively involved in writing software and building new things that will be controlled by it, making this an innovative addition to your STEM/STEAM or coding program. Students write code using one of the easy-to-use editors on microbit.org, connect their BBC micro:bit board to a computer via USB, then press the compile button in the editor and drop the downloaded file directly onto their micro:bit. Bluetooth® Low Energy connectivity allows the BBC micro:bit to wirelessly connect to mobile phones and tablets, take a selfie, or drive the music in a playlist. Based around a 32-bit ARM Cortex-M0 processor, BBC micro:bit is 18 times faster and 70 times smaller than the BBC Micro of the 1980s.

BBC micro:bit Features

  • Onboard accelerometer and compass sensors
  • Bluetooth® Low Energy and USB connectivity
  • Display consisting of 25 LEDs
  • 2 programmable, user-assignable buttons
  • Device input and outputs are through 5 ring connectors that are part of the 21-pin edge connector
  • Powered by either USB or external battery pack (external battery pack not included)
  • App available for Android™ devices
  • Comes in 1 of 4 color schemes (no color choice)

To use the piano, the BBC micro:bit should be inserted firmly into the edge connector, either way around. If the Link Header is being used, the BBC micro:bit LED display should be facing the piano keys. Power is provided via a 5V micro USB connector. Board then produces a regulated 3.3V supply, which is fed into the 3V and GND connections to power the connected BBC micro:bit, removing the need to power the BBC micro:bit separately. This also powers the capacitive touch sensor IC and audio amplifier.

Kit includes :KLEF piano, BBC micro:bit, and 39-3/8 in. L (1 meter) micro USB cable
