ARDUINO PROGRAM | VIDEO OPERATION
Technological Christmas decoration made with 56 RGB LEDs and controllable with any Arduino board (not included), ideal to be placed on top of the tree or wherever you want, for example on the door of the house.
The RGB LEDs are connected in cascade and powered in parallel; this configuration allows to address each single LED and choose the color individually among the 256 possible combinations for each RGB base color (so we have 256x256x256 combinations!) determining a total of 16,777,216 colors. The sketch that we have written and that you can download at the bottom of the page, allows you to generate different effects as soon as the power is supplied.
Power supply: 5 Vdc
Dimensions (mm): 148x148
ADDRESSABLE NEO LEDs |
NEO technology makes it possible to create “intelligent” RGB LEDs with on-board controllers, which can be easily integrated into the Arduino environment thanks to freely available libraries. A peculiarity of the LEDs is that they can be connected in cascade so that the data line passes from one to the next, but the price to pay is that beyond a certain number of LEDs, the management speed must be significantly reduced; because of this, if you have to make arrays to show fast graphics you need to use many lines with a few LEDs each. Each RGB LED can be managed individually by means of a special command inserted in the serial string and can produce up to 256 shades of its own color, resulting in a total of 16,777,216 color combinations. it is practically a solution that involves the integration of a driver and the respective RGB LED in an SMD case, allowing direct LED control for LEDs. The data channel used for communication with the LEDs and therefore with the strips is similar to the One-Wire type. The power supply for the LEDs is 5 volts; communication occurs at a maximum of 800 kbps. The system command protocol provides for the sending of groups of three bytes in a string of 24 bits, each of which contains the lighting status of each base color (first the eight bits of green, then those of red and finally those of the green). |
