The invention belongs to the field of science and education and advertising instruments, and particularly relates to a knob type LED color-changing module and an interactive wall applying the same. The knob type LED color-changing module comprises a rotating part, and the front face, facing an operator, of the rotating part forms an LED light-emitting face; the back surface of the rotating part extends backwards in the axial direction to form a rotating shaft, and the rotating shaft is in power connection with an input shaft of an encoder, so that the encoder is triggered to respond through the rotating action of the rotating part, and then the LED light-emitting face is controlled to generate follow-up color change, and therefore, on-line manual adjustment operation of various colors andbrightness can be simply and conveniently realized. Another purpose of the invention is to provide an interactive wall using the knob type LED color-changing module, i.e., the knob type LED color-changing modules are arranged
