VOLUME MEASUREMENT DEVICE

Hi there!

This was my first circuit design ever! I have tried to create a system with 6 LEDs and a microphone. The idea was to have a micro controller that would use the microphone as an input and find the volume of the sound. As an output it would light up LEDs according to the volume. If the volume is high it would light up 6 LEDs and if there is no sound the LEDs would not turn on. 

Unfortunately, I never got the chance to print this PCB and solder the necessary components and use it. Yet, I am still  proud of coming up with this design without any prior circuit or coding background.
