Abstract
Provided is a transmitter that includes a channel selector for modifying an operating frequency of a radio-controlled toy. The transmitter has a channel selection switch that enables a user to pick a channel from a set of predefined channels. The selected channel is then transferred to the toy. For example, a microcontroller unit within the transmitter may be used to detect the selected channel. The toy is placed in contact with the transmitter and the transmitter's microcontroller unit communicates the channel to a microcontroller unit inside the toy. The toy's microcontroller stores the channel in a memory in the toy. The toy then tunes to the stored frequency to receive control signals from the transmitter.
