USB-powered color temperature adjusting lamp strip control method and controller

The invention discloses a USB-powered color temperature adjusting lamp strip control method and a controller. The method comprises the following steps: S1, providing a working power supply for a lampstrip controller through a power supply access circuit; S2, enabling the MCU control circuit to generate a control signal according to the signal acquired by the acquisition circuit, and enabling thedriving circuit to control the switching of the lighting mode of the lamp strip according to the control signal; and S3, cycling the step S2 until the MCU control circuit receives a stop signal. The controller is connected with the double-color diode, multiple control modes are combined through forward and reverse voltages, the duty ratio of the single-chip microcomputer pwm and the power-on timeof the forward and reverse voltages, so that light emitted by the lamp strip generates different color temperatures, the overall effect is good, and the atmosphere is good. 本发明公开了一种USB供电的调色温灯带控制方法及控制器，包括如下步骤：S1、通过电源接入电路为灯带控制器提供
