Manual design matrix LED-it's certainly an ambitious project, burdened with a large risk of errors. First and foremost, is the soldering between individual LEDs and resistors and then combined them in rows and columns forming a matrix of LEDS and connections of the control system in the form of, for example, was programmed for the microcontroller. Such installation is very labor intensive, but you can make this process easy to get around with matrycom and at the expense of the LED, provide the store Botland. In our offer you will find accessories such as power supplies and controllers for strips and matrices of LEDS.
A matrix with 512 LEDs, arranged in 32 rows and 16 columns at intervals of 10 mm between the LEDs. The LEDs may be visible even from 12 metres. To connect with the microcontroller it takes 7 contacts. The matrix is supplied with the voltage of 5 V.
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.
Expansion Board for the BBC micro:bit, where there are 3 large 10 mm LEDs in the colors red, yellow and green. Tile has to simulate a fully working light alarm, created based on the module of the BBC micro:bit. The power led is delivered directly from the tile development micro:bit.
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.
Expansion Board for the BBC micro:bit equipped with RGB LED ring constructed of 24 individually addressed LEDs WS2812B. Supply voltage is from 3.5 V to 5 V. The outputs on the Board allow for direct threaded connection to the main module of the BBC micro:bit. The LEDs are arranged equally spaced on a ring with a diameter of 80 mm.
The matrix consists of 256 individually addressed RGB LEDs arranged in 8 rows and 32 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.
Module with 15 LEDs RGB WS2813 arranged in one row. On the Board is Grove connector for easy connection of the module with base plate. Each led is individually orientedfor management of the entire module need one pin of the microcontroller. The module supply voltage is 5 V or 3.3 V.
The module is designed to control and personalize the entire APA102 LED strip band directly from the SAMD21G-AU microcontroller board. LumiDrive is equipped with a USB-C connector capable of supplying up to 1.5 A from the USB 3.1 port, LiPo connector and charging circuit for portable power supply. The device has two...
The module is equipped with 20 LEDs RGB WS2813. On-Board Grove connector is for a simple connection to a base plate. Each of the diodes individually focused, to manage the whole just one pin of the microcontroller. The module is powered by 5V or 3.3 V.
A single chain of LEDs often has a width of approx. 10 mm and a length up to 5 m. Its structure allows the intersection between the LEDs, the components of its units. The LEDs are distributed along the chain, as a rule, from 50 to 120 LEDs per meter. The color and quality of the individual diodes affects the visual light effect in the chain of LEDS. On the other hand, the chain is factory-glued double-sided tape after removing it, you can stick a chain of LEDs to any surface. Since the electric circuit circuit LED flexible, it also allows you to install it on uneven surfaces with irregular structure. Such construction technology is characterized by multicolored LEDS, which is sufficient to connect one output of the microcontroller, to control them. Addressable LED strip allows a variety of lighting effects, in particular, the elements of decoration.
Tape and LED often supply a constant voltage of 5V, but there are also modules that can be powered with 3V or 12V. To do this, the easiest option would be the power supply is AC 230V. Choosing a power supply, you need to pay attention to its output power, so it was big enough for planned number of powered LEDs in the matrix or film LED. One of the ways to connect the LED strip connection chain, which is that each piece of LED strip must be connected directly to a power source or other parts of the LEDs, which is connected to the power source. The connection method depends on the geometry of the conductors and shapes of the connectors in tape LED and the shape of the output connector of the power supply - if you love soldering, it will be the most flexible and cheap way of installation. If you don't want to use a soldering iron, you can use the connectors that connect modules, LED lighting and power supplies, without soldering.
