Copy and paste the code in the Arduino IDE. LED_TOTAL) depending on the length of LED strip that you are using. Make sure to adjust the number of LEDs (i.e. It doesn't need buttons since there's nothing to toggle, but you can still use it to test your potentiometer. It only contains one visualizer and one color palette to keep things concise.

NeoPixel Arduino Library (ZIP) Simple Visualizer Programīelow is a small sample program to test if everything is connected properly with the simple and full circuit. If you want to take advantage of all the visuals, palettes, and shuffle mode, you can build the full circuit on the right. If you just want the LEDs to react to sound using one visualizer and one color palette, you can build the simple circuit on the left. The circuit should look something like the diagrams below. If you use a different pin, don't forget to change it in the code as well: Sound Detectorīetween Digital/Analog (A5) and DIN on LED strip The pins used in the diagram and the code are in parentheses. Trimpots are not polarized either, however their middle pin is the analog output, so don't power that directly.Resistors and pushbuttons are not polarized.Make sure to place the side with a white stripe and a negative symbol into a negative current (ground) and the other into positive current. Electrolytic capacitors are polarized, so how they are oriented is important.Bending the pins to hold the sound detector perpendicular to the breadboard is a recommended option. Be conscious of the orientation you think would allow the sound detector to take optimal readings for your intentions.

Before you begin, here are some things to keep in mind: If you've never soldered before, I highly suggest taking a look at this guide to solder.īelow is also a general chart for how the pin(s) on each component should be routed and an accompanying diagram. Depending on your setup, the project may not require any soldering! The few exceptions will probably be soldering some pins to the sound detector, and, if you've cut a roll of addressable LEDs in the middle, you'll have to solder some wires to the starting LED's pins.
