A presentation apparatus has an operating main body. The operating main body further includes a LED module and a control unit. The LED module is disposed on a surface of the operating main body. The control unit is electrically connected to the LED module, and controls the LED module to display a timing message in response to a timing signal, and then controls the LED module to display a warning message in response to a triggering signal when the timing signal exists, thereby achieving the objective that the presentation apparatus have multiple functions with low manufacturing cost.
