I have made a couple of other Scratch Online extensions, and chose to communicate with my raspi/Arduino combo using MQTT so as to avoid the problem of connecting to a device locally. the code actually becomes quite tidy
I thought I could combine the other scratch blocks I have with those of Makeblock to blend several types of electronic gadgets (a face tracker, a moving skull) in one student friendly project.
However, there is no way I can get the device plugin to work, i have now followed the guidelines for plugins at scratch.mit.edu and your youtube video, but there is always a red circle telling me that the makeblock scratch blocks can not connect. Have anyone else experienced this? Any solutions?
