MakeCode Setup Tutorial
You'll need
We've premade two example setups files for you.
MakeCode Example ONE : Play notes right away.
Plug in Micro:Bit to computer.
Basic Automatic Piano Setup HEX File
click EDIT
Download and Drag onto your MicroBit.
Wait for it to stop flashing. It will dismount & then remount.
Then EJECT the Micro:Bit (varies depending on Win or Mac ).
Unplug USB.
Insert Micro:Bit into Piano
Switch the USB cable to the top of the piano.
Play Piano !
MakeCode Example TWO : Learn individual key assignment
This example will open MakeCode & you can see how I assigned the capacitive touch based on these port numbers on the bottom.
Manual Key Assignment HEX File
click EDIT
Download and Drag onto your MicroBit.
Wait for it to stop flashing. It will dismount & then remount.
Then EJECT the Micro:Bit (varies depending on Win or Mac ).
Unplug USB.
Insert Micro:Bit into Piano
Switch the USB cable to the top of the piano.
Play Piano !
For this demo code, instead of octave shifting, the piano Arrow buttons, as well as Buttons A & B will display some fun LED Icons.
MakeCode Tutorial THREE : How Examples 1 & 2 were made.
Open MakeCode.
Expand ADVANCED > EXTENSIONS
Enter KLEF into the Search Bar. Select it.
You should now see the :Klef library in your Blocks
To recreate Example One.
To recreate Example Two Replace the FOREVER Loop with a nested If Else Loop. Assign Each Key & note. Refer to the back of the piano.
These will probably be easier to read by opening the MakeCode Example file linked earlier.
End of Make Code Blocks Tutorials.
Go make something fun!
Once you've mastered those tutorials & you love MicroPython & if you want to get more into direct c-like arrays & address assignment...
Alternate (Experimental) MicroPython instructions.
You'll need :
Open MU
LOAD the file Klef-piano.py off the Github repository.
Once you have the Code loaded, FLASH it to your Micro:BIt
Unplug Micro:Bit, insert into the :Klef and then insert the micro USB into the KLEF PIANO not the microbit. It will give you an error otherwise.
You can also think about using the onboard breakouts to control things via jumper wires.
You will notice the default volume is quite LOUD.
Now go make beautiful music all night long so your neighbors can hear.
