“A VU metre is volume unit (VU) meter or standard volume indicator (SVI) is a device displaying a representation of the signal level in audio equipment. It is used to visualise the Analog signal. I already made a VU meter using Arduino you can check here. In this Instructable I am going to improvise the look of the VU meter. Now I am going to instruct how to make a VU meter using Arduino with less number of components.”
