Is there a sensor that can output electrical signals at different frequencies when sound or music is played? I want to design a single-chip circuit and use a component that can output sound or music a...
Oops, I haven't been in the forum for a long time!
The reason is that my laptop graphics card is broken.
If it's broken, it's fine as long as it's fixed, but the problem is that I don't have the money...
