I wanted to make a system in which I can use the RGB sensor and the microphone simultaneously on Arduino Nano 33 BLE Sense. So I tried adding different blocks for both purposes and the training results were pretty good with accuracy of about 98%.
But when I wanted to test it using live classification it started giving me errors. I had made the frequency 16000Hz for both - the microphone and the colour sensor.
The errors were -“Cannot process file, impulse requires axis “audio”, but not present in this file (found: “R”, “G”, “B”) - note: axes are case sensitive.” I pretty much understand the error but I cant find a solution.
If anyone has a solution to this then you are welcome.
