How To Make Amazing RGB Ring Light

Hello friends, this is a RGB ring light for your lovely table using old plastic jar , PVC pipe and RGB led. In this project I used WS2812B LED strip for light and arduino nano to control led strip. Here I used total 35 Nos led but you can increase number of led just change the number of led in code before uploading.

Components :

1) ws2812B led strip 60led/m : https://roboman.in/qtch
2) ws2812B led strip 30led/m : https://roboman.in/6r9a
3) Micro USB Socket : : https://roboman.in/7pas
4) Arduino Nano: https://roboman.in/59h4
5) Arduino Nano Type C : https://roboman.in/xkfu
6) SPST Switch : https://roboman.in/74he

// animations patterns and have them automatically rotate.

// Additional notes on FastLED compact palettes:
//
// Normally, in computer graphics, the palette (or "color lookup table")
// has 256 entries, each containing a specific 24-bit RGB color.  You can then
// index into the color palette using a simple 8-bit (one byte) value.
// A 256-entry color palette takes up 768 bytes of RAM, which on Arduino
// is quite possibly "too many" bytes.
//
// FastLED does offer traditional 256-element palettes, for setups that
// can afford the 768-byte cost in RAM.
//
// However, FastLED also offers a compact alternative.  FastLED offers
// palettes that store 16 distinct entries, but can be accessed AS IF
// they actually have 256 entries; this is accomplished by interpolating
// between the 16 explicit entries to create fifteen intermediate palette
// entries between each pair.
//
// So for example, if you set the first two explicit entries of a compact 
// palette to Green (0,255,0) and Blue (0,0,255), and then retrieved 
// the first sixteen entries from the virtual palette (of 256), you'd get
// Green, followed by a smooth gradient from green-to-blue, and then Blue.

// Additional notes on FastLED compact palettes:

// Normally, in computer graphics, the palette (or "color lookup table")

// has 256 entries, each containing a specific 24-bit RGB color. You can then

// index into the color palette using a simple 8-bit (one byte) value.

// A 256-entry color palette takes up 768 bytes of RAM, which on Arduino

// is quite possibly "too many" bytes.

// FastLED does offer traditional 256-element palettes, for setups that

// can afford the 768-byte cost in RAM.

// However, FastLED also offers a compact alternative. FastLED offers

// palettes that store 16 distinct entries, but can be accessed AS IF

// they actually have 256 entries; this is accomplished by interpolating

// between the 16 explicit entries to create fifteen intermediate palette

// entries between each pair.

// So for example, if you set the first two explicit entries of a compact

// palette to Green (0,255,0) and Blue (0,0,255), and then retrieved

// the first sixteen entries from the virtual palette (of 256), you'd get

// Green, followed by a smooth gradient from green-to-blue, and then Blue.
