Ws2812b is an intelligent external control LED light source integrating control circuit and light-emitting circuit. It has built-in RGB three-color light beads. Each light bead control requires 24 bits of data. 8bit green brightness + 8bit red brightness + 8bit blue brightness. The three primary colors of each pixel can realize 256 levels of brightness display and complete the full truth color display of 16777216 colors. A plurality of lamp beads can be combined to form a lamp belt. The lamp beads on the lamp belt are powered in parallel and the signal lines are "connected in series". The signal enters the lamp bead from di. After locking 24bit data, the lamp bead shapes and amplifies the remaining data and outputs it to the next cascaded lamp bead through do port. After each lamp bead is transmitted, the signal is reduced by 24bit. When the light bead receives 280 μ S above reset data, the lamp bead completes the control of RGB three-color lamp according to its own locked data.
