Hardware; with tags for motors, cnc and maybe power.
In the suggested structure in above topic, there will no longer be a Installation and Troubleshooting ![]()
Programming Questions are 'officially' about the (C++) language; from that perspective I do not think that it should be combined with Project Guidance. Hence incorporated in Your Project above.
Good one
I would in that case split multiplexing related stuff off and move it to General Electronics (although things like software based multiplexing don't fit quite in there).
I don't see a relation between the 4; Audio can still be considered to be part of sensors when it comes to audio-in; but players not so much.
I've been thinking about sections for Input devices and Output Devices; Motors, Mechanics, Power and CNC could be part of the latter together with Displays.
I know; the mock-up that I presented in Restructuring forum categories - #55 by sterretje used smaller ones and moving the title next to it also helped. One however possibly gains more from removing the right column with the latest topics.
Thanks for the feedback.
