Description
A package of five NeoPixel WS2812B LEDs, through which you can easily add colorful visuals to your project. The LED includes a built-in controller that allows you to control with one line connected to a microcontroller, e.g.Arduino,STM32orRaspberry Pi. Because each led has an individual address, on the same bus you can connect several elements.
|
The product is compatible with Arduino Company Adafruit provides a library for users of ArduinoNeoPixelandNeoMatrix. The network can also be foundin the Pololu library. |
Connection
The LED has four pins, as shown in the photo below. When the connection is enabled, by default it is in blue color.
| Pin | Description |
|---|---|
| 5V | The supply voltage of 5 V. |
| GND | The ground of the system. |
| DIN | The control input that must be connected to the controller, or prior LED in the chain. |
| DOUT | Additional output for connection of another LED. |
Below are a few tips that can help to protect your diode from wear out:
- Never connect voltage higher than 5 V.
- Connecta capacitorwith capacity not less than 10 UF between the power pins.
- Avoid changes in work if the power is turned on.
- Use as short as possible wires on the line of control between the LEDs and the microcontroller.
- Consider the use of a resistor in the range of 100 Ohms to 1000 Ohms on data lines between the microcontroller and the diode, in order to reduce noise and prevent accidental powering of LEDs with the contact of the processor.
|
Attention! LEDs can explode if the voltage exceeds the permissible value. Supply voltage 6 Volts can cause permanent destruction of the diode. |
