Battery Powered

Introduction: Battery Powered

For the Battery Powered contest, we're making an audio-responsive LED Cloud decoration. It looks like a cloud but the LED's pulse to the beat of whatever song you're listening to.

Supplies

  • Arduino Uno
  • Solder
  • Breadboard
  • LED Strip
  • Glue gun
  • glue sticks
  • 12V Battery
  • PLA
  • Structural material
  • clothes hanger

Step 1: Designing the Structure

In order to CAD the structure, which would be the foundation of the design, many different measurements were taken. The measurements of our cylindrical base would have to be taken to CAD them and create brackets to connect them.

Step 2: Assemble the Circuit

For the circuitry, there were some very basic calculations done to find the voltage needed to provide consistent power to the electronics. Ohm's Law equation was used to determine those values. These were all taken into account and a proper circuit was assembled.

Step 3: Printing the Connectors and Assembling the Structure

After designing the brackets and printing them, I attach them to the cylindrical structure pieces and zip tie a piece of corkboard to act as a base for the Arduino. I then screw the Arduino components into the corkboard and use a wire clothing hanger to create a place to hook the whole structure.

Step 4: Coding the Arduino

The code in the first image is used to individually increment the intensity of each LED color to create a wide variety of colors that will flash. The code in the second image displays a method used to increase and slow down the speed at which the lights using digital output from our sound sensor.
