A remote controller including buttons, an input module including resistors and switches, and a control module including a determining module, a storage module, and a modulation module. Each resistor is coupled to a power source and provides a current path corresponding to one button. The switches are coupled to the resistors. The corresponding switch provides the corresponding current path when one button is pushed. The input module accords with the corresponding current path to generate an input signal. The control module generates an output signal according to the input signal. When the input module transmits the input signal, the determining module obtains the pushed button according to the input signal and generates a determining signal according to the obtained result. The storage module generates a control signal according to the determining signal. The modulation module modulates the control signal to generate the output signal.
