Thank you dave and the rest of you guys! presenting it to my peers tomoro so i will check back with how it went! much thanks!

Basically i just need help understanding what the reference dc voltage connected to the top LED is for, what the variable resistor is for, and basically how the overall circuit works (meaning how the output is created through the lm3915). sorry about the mix up!

If anyone could help, that would be amazing. its not homework, its a personal project i am undertaking and just wondered if anyone could give me an explanation or any help if they had any understanding of this circuit! thanks guys! Samm
