Make your room awsome by this diy spiderweb audio spectrum,the web part is little bit time taking but in the end the results will be good and
astonishing

more diy audio spectrum n many more coming soon ,for videos you can follow me on Instagram @shubham_z0m

Step 1: Spiderweb Part

the web is made by smd led on each connection, three led connected in series in horizontal direction and one signal wire is connected on each series led on positive terminal,the vertical wire is for ground ,signal wire is twisted for better support
