MCookie-LED Matrix

Outline mCookie-LED Matrix module integrate 6 WS2812 LEDs, each of which has an IC control chip. Them are controlled by a single bus, and the lighting status of each of them is controlled by an I/O port, which can be used as a full-color module to provide light source. Features Single bus control, only need one I/O port to control, and complete data receiving and decoding; Built-in IC control, serial cascade interfaces which can be cascaded controlled; The three primary color of each pixel can realize 256 level light display, and complete 16777216 colors whole true display, and the scanning frequency is no less then 400Hz/s; Built-in power on reset circuit and power down reset circuit. Specification Electric specification: Working voltage: 5V; Controlling light source: WS2812*6. Technical parameters: WS2812 type; Gray of three primary colors: adjustable 256 level; Size of LED: 5mm*5mm; The speed of data sending can reach 800Kbps. Connection: Direct adsorption on other modules; Connect to A0 interface by default. 600px 600px Document File:Ws2812.pdf Further reading on the neopixel library: https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library Development Equipment Module Number Function mCookie-CoreUSB 1 Core board mCookie-LED Matrix 1 Lamp matrix Other equipment USB cable*1 600px Preparation Connect CoreUSB with LED Matrix, and link them to the computer with USB cable. 600px Experiment 1：Light up the Lights Open Arduino IDE, delete the original code in the IDE, and copy the following code to IDE. #include <Adafruit_NeoPixel.h> #define PIN A0 //led control pin #define PIN_NUM 6 //Number of leds allowed to be connected Adafruit_NeoPixel strip = Adafruit_NeoPixel(PIN_NUM, PIN, NEO_GRB + NEO_KHZ800); void setup() { strip.begin(); } void loop() { strip.setPixelColor(0, strip.Color(255, 0, 0));//Red strip.show(); delay(1000); strip.setPixelColor(1, strip.Color(0, 255, 0));//Green strip.show(); delay(1000); strip.setPixelColor(2, strip.Color(0, 0, 255));//Blue strip.show(); delay(1000); strip.setPixelColor(3, strip.Color(255, 255, 0)); strip.show(); delay(1000); strip.setPixelColor(4, strip.Color(0, 255, 255)); strip.show(); delay(1000); strip.setPixelColor(5, strip.Color(255, 0, 255)); strip.show(); delay(1000); } Choose the right board and COM port Compiling When compiling, it will prompt to save the project, and the players can save to your folders named by yourselves. Download After the success of the compilation, you can directly download. Prompting download successfully means that you have completed the download. 600px The result is there will be one light shows every 1s, until all of them light. Program Description Use "Adafruit_NeoPixel.h" library to drive lights; "#define PIN A0" defines the controlling LED pin, which can be transferred out through the Hub, and can be changed be the users; "#define PIN_NUM 6" defines the number of leds allowed to connect; "strip.setPixelColor(i, strip.Color(R, G, B));" function declaration: i: Which light. Starting from 0 to be taken as the first light. R: The red value（0-255）; G: The green value（0-255）; B: The blue value（0-255）. "strip.show();" shows LED display. Other Controlling Methods Reference code: LED_Matrix Application LED full-color light-emitting word LED string, full-color module, LED full-color soft light bar and hard light bar, and LED guardrail tube. LED point light source, LED pixel screen, LED special-shaped screen, all kinds of electronic products, and electrical equipment entertaining diversions. Purchase History Gallery Video
