Description
Individually addressable RGB LEDs placed in a 5 meter strip with a density of 30 diodes per meter. Each pixel can emit a colour from a 24-bit palette.
The diodes are arranged densely at a distance of approx. 28 mm, so the brightness is high. The system is powered by 5 V, takes about 1.8 A per meter (9 W). The chain can be cut after each diode.
Connection
The device has a 4-pin connector consisting of the following leads:
- GND (white wire) -module ground
- 5 V (red wire) -supply voltage, for one matrix a source with a current capacity of at least 3.5 A for each meter of chain should be connected
- D0 (green wire - date) - digitalcontrol signal from the microcontroller
- B0 (blue wire - clock) - digitalcontrol signal from the microcontroller - connected according to the program needs

First start-up - example of ColorPalette
- Run the test program by selecting in Arduino environment:
- File ->Examples ->FastLED ->ColorPalette
- Select the pin from which the LEDs will be controlled. The default is pin 5:
- Line 3#define PIN 5
- Select the number of pixels to be controlled. The default is 50:
-
- Line 4#define NUM_LEDS 50
- Select the brightness at which the LEDs should light, the default is 64:
- Line 5 #defineBRIGHTNESS 64
- Select the type of LED driver, the default is WS2811
- Line 6#define LED_TYPE WS2811
- Upload the program to Arduino. Pixels should all light up and change colors from the color palette.
