This instructable was created as part of the Instructables Build Night with Chibitronics at MakeICT.
We received Chibitronics peel-and-stick electronics for crafting circuits for an Instructable Build Night. These circuit stickers allow anyone to add effects to just about any item you can think of using lights (LEDs). Included were effect and sensor stickers so the lights can do more than just being on, they could be animated or influenced by external input such as making a sound or touching an item. It was with an effect in mind that we built something that was affected by the environment around it, a library sound meter.
Step 1: Preparing to build the sound meter
For this project you'll need:
The effect sticker has three corners that stick to the copper tape: one corner is positive (shown as +), one corner is negative (shown as -) and the third corner is called the signal that generates a light pattern. The signal is pre-programmed to affect the lights connected to it on based to the amount of sound that is generated.
Step 2: Building the circuit
We are going to use the sound sensor template that Chibitronics has created. The space between the lines where the LED stickers go is just 1/4" and using the template has the right spacing. The effect stickers are a little bit trickier when laying out the copper tape since they are farther apart and have three corners.

Step 3: Assemble the sound meter
Build your Library Sound Meter with any artwork you like. The owl was chosen as the bird is wise and quiet, a perfect animal for any library.
