Light emitting diodes are semiconductor electronic devices that emit light in monochrome, when contained in this element PN connector electric current runs. If in one case put three LEDs - red, green and blue, by controlling the relative brightness of each of them, perhaps a smooth change of the resulting color of the led. In our store there are many diodes of this type, the so-called RGB. They are different housings, brightness, and, in some cases, a built-in adresowalnym controller digital RGB channels.
The matrix consists of 64 individually addressed RGB LEDs arranged in 8 rows and 8 columns. Each pixel may emit a color from 24-bit palette. For control the module needs just one microcontroller output. The matrix is made of an elastic material that allows you to bend it.
The ring quarter consists of 12 individually addressed RGB LEDs WS2812 5050 with integrated control unit. Module needs one microcontroller output. The outer diameter of the circle consisting of four parts is 158.0 mm.
Gravity: Digital module LED RGB is a cascading interface, compatible with LED tape. Due to its construction it provides an easier way to connect the individual modules to control, you only need one pin code, whereas standard tape needs three. This can significantly reduce energy consumption.
The matrix consists of 256 individually addressed RGB LEDs arranged in 16 rows and 16 columns. Each pixel may emit a color from 24-bit palette. For control the module needs just one microcontroller output. The matrix is made of an elastic material that allows you to bend it.
Development board is intended for designing interactive electronic circuits embedded in the so-called "smart clothes". Equipped with li-pol battery charger and 24 fully programmable RGB LED. Fully compatible with Arduino.
LED module lights up in the seven colors of the rainbow. The controller randomly chooses the color. Modules may be connected in a cascade, one interface can control all the LEDs. The module requires no programming, just turn on the power to the LED.
The emission color of the led depends on its construction, and more specifically from the semiconductor material of her plug PN. About the energy emitted from the led elektroluminescencyjnej photon decides the break energy of the material - this affects the wavelength of the photon, that is its color. Like that you can't change the break energy efficiency in the finished diode to control the color of emitted light are used LEDs RGB in one structure this system has three LEDs - red (Red), green (Green), and blue (Blue). The RGB model is addytywnym model, in which the light of red, green and blue can be added for himself to play a wide range of colors.
Light emitting diodes are driven by current signal is a current, not applied voltage causes elektroluminescencję connectors PN in led. If current stabilization the simple is the digital test is more complex. Therefore, to control the brightness of LEDs is used instead of the digital controlled current sources, regulators PWM. Such systems modulate the current flowing through the diode signal of a rectangular shape variable load. Adjusting the percentage of time that lights, adjustable brightness - LEDs turn on and off so fast that the human eye does not notice the flicker, but only the average emission rate at the moment.
The RGB LEDs with integrated controller, it's a smart light source that can be digitally controlled. In one feature, but three LEDs, built-in url trójkanałowy controller LEDs. It has a digital input, which allows the transfer of data and control the relative brightness of each of the integrated LEDs. Moreover, these elements can be connected in cascade. Each driver has a 24-bit buffer hatch that controls the brightness of each led (eight bit per led). Still transmitted via the serial interface to the item data is passed to the next led using only one GPIO line, for example, a microcontroller or computer jednopłytkowego.
