LED stripe shows no reaction to input from piano #602
Hey guys, i found this amazing project!!!! i wanted to build it for my daughter. I bought all components that were suggested and followed the instructions.
The raspberry pi is running. I can connect to the web-interface from there i can run the LED demo schemes that are installed. Like the fireplace etc. It's working fine!
Until I connect everything to the piano or even tried a guitar...no LEDs are moving.
I made sure the input port is set to the MIO (iconnectivity).
I even went into the Python screen and checked that the MIO i connectivity is even recognized at the USB port. And it is.
So I have no clue anymore what to do. I hope you can help me?
I would really appreciate that 🙏
To be honest I’m fighting with leds for a good week now and I’m close to give up - I’m ended up with this setup (with CD74HCT125E as level shifter) and led strip still is not stable (I’m using raspberry pi zero not arduino of course)
