Music Equalizer Display: Hardware

Hardware Design
           In the last section we saw a quick look at the schematic put together. Now we'll take a bit of a closer look at it. The wiring is pretty straight forward and follows the schematic exactly.

           Again, the yellow wire is for the audio input signal which will be generated by a laptop (or cd/mp3 something).

           Somewhat fortunately this project is more heavy on the software so once the circuit has been correctly wired on the breadboard we can jump right into the code which again isn't too bad. Make sure you wire the voltage divider correctly and that the speaker has one lead attached to the audio in and one lead attached to ground.
