The 8-Piece Ultra Bright RGB Rainbow LED Ring features 8 ultra bright RGB LED beads arranged on a circular panel. This ring has an outer diameter of 1.25 inches (32mm) and an inner diameter of 0.62 inches (16mm). It's chainable, with the output pin of one bead connected to the input pin of another on the panel. You can control this LED ring using an external device via the built-in microcontroller pin. Each bead on the panel is addressable due to its internal driver chip, allowing you to program them to shine in different colors. With about 18mA constant current drive per LED bead, the brightness remains consistent. You don't need to add external choke resistors even when the voltage changes. To operate the ring, power it with 5V DC (or within 4 - 7V range). Features: 1. 8 ultra bright LED beads on a circular panel with specified dimensions. 2. Chainable design. 3. Controllable by a microcontroller. A single data line with a timing - specific protocol is used. It requires a real - time microcontroller like AVR, Micro:bit, Arduino, PIC, mbed, etc., and an 8MHz or faster processor. It's not suitable for Linux - based microcomputers or interpreted microcontrollers such as netduino or Basic Stamp.
Using this 8 - piece RGB LED ring is easy. First, make sure to power it up with a 5V DC power supply, though it can work within a 4 - 7V range. You'll need a real - time microcontroller like an AVR, Micro:bit, or Arduino to control it. Each LED bead can be programmed to show different colors because they're addressable. Remember, this ring has a chainable design, so you can connect multiple rings together if you want. When programming, keep in mind that the protocol is timing - sensitive, so a fast enough processor (8MHz or faster) is required. Avoid using Linux - based microcomputers or interpreted microcontrollers as they won't work well. As for maintenance, there's not much to do. Just keep it away from excessive moisture and physical damage. If you notice any issues, check the power supply and the connections between the beads and the microcontroller.
