This is a Smart LED light stick that contains 20 x WS2812B single wire addressable full colors RGB LEDs and Atmega328 microcontroller. These full colors chainable intelligent RGB LEDs work with a single wire addressable protocol thus they require a micro-controller to generate the pulse train to control the colors and flashing effects. Refer to the datasheet of LEDs to decode the various colors flashing effects. The operating supply of the circuit is 5V DC with a maximum current of 1A.
Example Arduino code will help you to test the board. The Atmega328 chip can be programmed using the Arduino platform, we have used the DIP package of the microcontroller for easy programming using Arduino UNO and insertion of the programmed chip to the LED stick.
- Digital pin D2 controls the LEDs, and Analog pin A0 provided to interface a sensor or switch.
- Operating Supply 5V DC / 1Amp
- PCB Dimensions 156.37 x 13.81 mm
Boot-loader/Arduino Programming Atmega328 is available here: https://www.arduino.cc/en/Tutorial/BuiltInExamples/ArduinoToBreadboard
WS2812B is an intelligent control LED light source that the control circuit and RGB chip are integrated into a package of 5050 components. It internal includes an intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent. The data transfer protocol uses a single NZR communication mode. After the pixel power-on reset, the DIN port receive data from the controller, the first pixel collects initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited to the signal transmission, only depend on the speed of signal transmission. RESET time>280μs, it won’t cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU. Refresh Frequency updates to 2KHz, Low Frame Frequency, and No Flicker appear in HD Video Camera, it improves excellent display effect. LED with low driving voltage, environmental protection, and energy-saving, high brightness, scattering angle are large, good consistency, low power, long life, and other advantages. The control chip integrated into the LED above becoming a more simple circuit, small volume, convenient installation.
hope to get a rep soon
Sorry this is not available.
can you help me make the algorithm flowchart?
I need to understand the code easily
Thank you very much
