I need an dual(stereo) LED level indicator of 100 LED/channel controlled by Arduino maybe Nano or something small like it. Something similar to this video [login to view URL] The LED's I will use are not like in the video, so you have to design the drivers also. Instead I want to use the classic 10 LED bar. I have to be able to control the LED brightness and have a few modes, like classic bar, peak-hold, single LED, Peak flowing to the top, and mid-start. Arduino has to display signal in audio mode, logarithmic non-linear and have a range of 70-80 db. You will deliver the schematic, and one channel video demo on a bread board will suffice to consider the project completed.
