Hello. This is correct command to start Visualizer: sudo python3 /home/Piano-LED-Visualizer/visualizer.py

When I enter that command, nothing happens. pls help see these for reference: https://drive.google.com/file/d/1fyiKP462tv508VtBawZHUMJJ6hyFNBr_/view?usp=sharing https://drive.google.com/file/d/1aC6PfVgtsPtFrV3nV3IHopA1brOtsZhx/view?usp=sharing

@ishchawla Do you have crontab configured so Visualizer starts on boot? If yes then type sudo pkill python3 it will stop any running python3 scripts. Then start visualizer.py script and look for errors in output.

Im not sure about that, I just used the preconfigured system image because I was having some issues while manually installing it. Should I still go on and type the pkill python3 command? Also, the visualizer.py script for starting is the one you mentioned above right? This sudo python3 /home/Piano-LED-Visualizer/visualizer.py one?
