I made a light and music setup to render music in real time. At the ends there are connectors for connecting the next tape, that is, you can lengthen the garland. The backing is available in white and black. It can be cut into several pieces if necessary. I purchased a 1 meter tape with 144 LEDs.

Arduino (Uno.Nano, Pro mini) is perfect for its role. The tapes themselves do not glow, they need a microcontroller. It is recommended to choose power supplies with a small power reserve. The diode controllers consume a little more.Īpproximate peak consumption for 1 meter tapes:ģ0 diodes per meter 9.5 watts (slightly less than 2A at 5V)Ħ0 diodes per meter 19 watts (3.6A at 5V) From here it is easy to get the maximum consumption of the entire strip by multiplying 60 milliamperes by the number of LEDs. The maximum power consumption is 60 milliamps, when all three diodes are on, it turns out to be white. Each of the LEDs (red, blue, green) draws 20 milliamps at maximum brightness. An external controller is required for operation, Arduino is quite suitable for this role. They are produced in the form of individual LEDs, strips, rings, matrices, etc. A total of 16 million colors and just one control wire. There are 255 levels of brightness available for each color. Arduino is perfect for this role.Īrduino or Raspberry PI will do. The diode controllers consume a little more.
Collected in one case RGB LEDs and a controller.

What is ws2812b? This is the second generation of individually addressable full color LEDs, also known as NeoPixel. Note: The power supply or controller does not include each LED is individually addressable, with 8 bits of green, red and blue data shifted over a 24-bit color 5050 SMD w / ws2811 IC built in144 RGB LEDs per meter each LED is independently addressable, opening up completely new lighting possibilities. Based on high quality SMD5050 RGB LEDs insert (built-in) integrated ICS control ws2811. Fine, high quality intelligent lighting! The Chinese gave the following parameters: I wanted to use it in different ways: as a decoration or a garland for the New Year, or as an independent CDU. This makes the New Year holidays even more suitable. It was always interesting to try the ws2812b LED strip. The encoder button is used to select a channel and is connected to pin 1, which is set as input. The direction of the encoder signals A and B are read using elements 2 and 3 that are connected to the module. The transistors are driven by pins 9, 10 and 11, which have internal PWM functions. It reads input data from the encoder and according to this information, the transistors are switched. The main controller is made using Arduino Uno. Thanks to this function, we can get a huge number of different colors using RGB LEDs and of course the resulting color can be dynamically changed using the regulator. Although they are in the same package, each die can be controlled independently. RGB LED is a very common type of LED strip that includes red, green and blue led chip in one case. For example, the IRF540 transistor has a quite low RDS pass-through resistance - about 70 mΩ. Transistors with low switching resistance, create very low heat dissipation even with the use of a large number LEDs.
Rotating the encoder on the board allows the user to select desired channel and change its brightness. Thus, you can create any color by mixing different colors in percentages. It can change the level of each color independently by changing the PWM duty cycle. This simple Arduino project is designed to be controlled using PWM (Pulse Width Modulation).
