Description
The ring consists of 12 individually addressed RGB LEDs with integrated controller. The module needs single pin of the microcontroller, e.g. an Arduino. The LEDs are arranged at equal distances on the circumference with an outer diameter of 37 mm. Each of them consumes a current of 18 mA, which in this case gives a total value of approx. 220 mA. The ring can be powered with a voltage from 4 to 7 V.
The used communication Protocol allows the serial connection of the LEDs. Another circuit should be connected to the output connector, combining with each other respectively, 5V, GND and OUT with IN. The manufacturer notes that when working with more than 500 LEDs, there may not be enough RAM in the Arduino Uno system.
Connection
The device has four terminals:- GND - module's ground
- VCC supply voltage 18 mA current for one diode
- IN the digital control signal from the microcontroller
- OUT - output to connect the next ring
