Doing a demo sometime in July at Hack Sounds in Sydney on this robot. The supplied Makeblock software for the Windows 10 PC, MusicBot no longer works but my own node-red software is still ok. I have modifed the Arduino firmware to extend the coms protocol. One reason Makblock PC software does not work could be that it does not recognise a com port beyond 20 but I have not verified this yet. I also get the same problem on the latest MakeBlock Scratch software.
