Neopixel Lamp

For my final assignment I decided to build a lamp using a neo pixel ring. This builds upon my previous light controller assignment.

Design Challenge

Make a device to control a light with the following features: 

  • A control to turn the light on and off. When it turns on, it should retain the relative red, green, and blue brightness levels from when it was last turned on.
  • The ability to fade each color channel (red, green, and blue) from off to full brightness
    • Fade level should be maintained when you release the fade controller
    • Fade should be interrruptable by other controllers, e.g. on/off or another fade controller
  • The ability to fade the overall brightness of the light

Inspiration

I saw this wall mounted light display and wanted to recreate it. 

Materials

Adafruit Neopixel

2 potentiometers (one to control the color hue and the other to control brightness)

1 button – on/off switch

Arduino

Battery

Plywood

Acrylic

Coding the Light Effects

I need to create code that controlled an on/off button, a potentiometer to control the color switching and another to control the brightness. Since the design of my light inspiration is sleek and simple, I opted to also keep the controls simple. Having never worked with neopixels this proved to be a confusing process. I had lots of examples to reference but was not quite sure what the code was saying until I uploaded each to my arduino and wired breadboard. This gave me some sense of what the commands of the neopixel library meant – but did not end the frustration.

Fabrication

I used plywood for the sconce. I design the back of the sconce with a pocket to house the controls (seen in the images below). I used two frosted plastic containers from Muji for housing the components on the back of the light.
