The RGB LED Module SMD 5050 KY-009 is a board that aims to facilitate the implementation of small projects with an RGB LED. This module consists of an SMD RGB 5050 LED and already has the connection terminals that are identified. The RGB LED has the ability to display a large number of colors that originate from three primary colors. The 5050 SMD is actually a 'tri' chip, meaning it has three smaller chips in every SMD. So each white LED actually has three white chips inside. 5050s can also be used for color-changing LED tape, with red, green, and blue chips inside each LED.  where each LED represents a different color: red ( Red), green ( Green), and blue ( Blue). Each of these LEDs can be individually controlled and if combined they can generate different colors.

- Specifications and characteristics:

- Operating voltage (red): 2 to 2.5VDC
- Operating voltage (green): 3.2 to 3.6VDC
- Operating voltage (blue): 3.2 to 3.6VDC
- Operating current (in each LED): 20mA
- Configuration: common cathode
- Wavelength (red): 620nm
- Wavelength (green): 520nm
- Wavelength (blue): 470nm
- Light intensity (red): 200 to 300 mcd
- Light intensity (green): 1000-1320 mcd
- Luminous intensity (blue): 200-285 mcd
- Operating temperature: -40º to 85º celsius
- Opening angle: 120º
- Brightness: 14 lumens

- Applications:

Projects with Arduino or other microcontroller platforms that require an RGB LED to signal something through different colors and without the need to use an LED for each signaling.

- Practice proposal:

Use the RGB LED Module SMD 5050 KY-009 in conjunction with the Arduino and mix the primary colors to generate several other colors.

- List of necessary items:

01 - Arduino with USB Cable

01 - SMD 5050 RGB Led Module KY-009

04 - Male-female jumper cables
