Arduino Acrylic VU tower

thingiverse

For some reason I had an issue uploading the video to thingiverse. Anywho, I designed this acrylic VU tower that plugs into an audio port and a speaker. Pretty cool works well. You'll need 3/8" thick slabs of acrylic 3"x5" they're friction fit so its going to be tight. I printed two acrylic holders and krazy glued them together. then glued the base to it. You will need an audio spliter, extra audio cable with 2 wires ( not sure what its called ) 5mm LEDs will fit. Source code for the arduino I found online by Kenny Vanpaemel and messed with it to work with mine. int led[10] = { 3, 4, 5, 6, 7, 8, 9, 10}; // Assign the pins for the leds int leftChannel = 0; int left, i; void setup() { for (i = 0; i < 8; i++) pinMode(led[i], OUTPUT); Serial.begin(9600); } void loop() { left = analogRead(leftChannel); Serial.println(left); left = left / 10; if (left == 0) { for(i = 0; i < 10; i++) { digitalWrite(led[i], LOW); } } else { for (i = 0; i < left; i++) { digitalWrite(led[i], HIGH); } for(i = i; i < 8; i++) { digitalWrite(led[i], LOW); delay(0); } } } Should work.
