Hi, so i watched this video
about using arduino to turn on light with clap.
However i am more curious of how it really works, i dont get the part where it uses amplifier to increase the DC offset. What exactly
does the DC offset do.
PS: i understand that the amplifier amplify the signal so that there are more voltage steps to work with.
