Make Your Own Wireless RGB VU Meter With Nice Light Effects

Hi friends, This is new and very compact DIY Wireless RGB VU meter with multiple color effects for when not using as a vu meter. This is totally wireless, no need to connect any device with this also this is rechargeable. You can control brightness and sensitivity using potentiometer. This very cool idea for your home decoration.

Amazing and Super Cool DIY RGB LED Cube

Hello friends, this is very cool project using RGB LED strip and glue stick. New look RGB light will provide you good look on your table. In this projects I used WS2812 addressable RGB LED, so it is very simple to handle Colors on this light.

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

// 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.

Amazing Colorful RGB LED Clock

Hello friends, this is RGB LED clock. You will get the time in 12Hr format and changing color of number automatically. In this project we used WS2812B LED strip which is available in online market easily. Also you can change the time from key. Here you will get five no of key to set time and color pattern. If you want to make this then just follow all the step and make your own RGB LED clock.

// 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.
