Microduino-Color LED

Language	English

Microduino-Color led Microduino-Color LED is a colored LED light with an built-in IC control chip, which can be cascaded arbitrarily. With only one I/O port, you can control all the lights. Each light can be controlled separately. Features The chip adopts 5050 package, including control circuit and RGB chip inside. With single bus control, you only need one I/O port to receive data and decode; With built-in IC control, serial cascading interface, it can have cascade control. Each pixel's trichromatic color can achieve 256-level brightness control, completing full display of 16,777,216 colors and the scanning frequency is not less than 400Hz/s; With built-in power-on and off reset circuits; ultra low power and ultra long life. Specification Electrical specification Operation voltage: 3.3V~5V Output device Tech parameter Adopt WS2812 integrated light source control; Each pixel's RGB can realize 256-level brightness display. When refresh rate is 30 frame/s, the cascade number is not less than 1,024 points. When the transmission distance of any two points is within three meters, there is no need to add any circuit. Size Size of LED：5mm*5mm， Size of the board:20mm*20mm 1.27mm-pitch 4Pin interface connects with Sensorhub. Connection method System and LED（IN）：System LED control needs to connect the signal of Sensorhub to the " big>IN</big>" base board of the LED. LED Cascade（OUT）： The first LED's OUT connects to the next LED's IN. Document 文件:Ws2812.pdf Development Preparation Make sure you build Microduino development environment. If not, please refer to: Microduino Getting started Core selection 1. Adopt Microduino-CoreUSB or mCookie-CoreUSB. 2.Adopt Microduino-Core or Microduino-Core+ as the core board and use Microduino-USBTTL to download program. Program Open " strandtext " in the libraries. 文件:MCookie-strandtext.JPG 800px "#define PIN 6" defines the pin which controls LED. "6" means Microduino's D6 pin, which can be converted by Sensorhub. Users can also change that according to personal needs. The number "60" in " Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800);" is the light number you want to cascade. " colorWipe(uint32_t c, uint8_t wait)" Function Description: " uint32_t c " defines the color of the lights and the format is " strip.Color(R, G, B)". R：Value of red（0-255） G：Value of green（0-255） B：Value of green（0-255） " uint8_t wait " defines delay time of a single light. The light number is defined at the beginning. Example: colorWipe(strip.Color(255, 0, 0), 50); Display red. Users can adopt the related tools to change color color。 “rainbow()” and “rainbowCycle()” are cool color pattern. Hardware Buildup Connect IN port on the back of the color LED to the D6 digital port of Sensorhub, which is also the definition and control of LED pins mentioned above. (Users can change according to personal needs.)
