Radio-controlled (RC) toys use a transmitter and receiver to communicate with each other. The transmitter is held by the person controlling the toy, and the receiver is located inside the toy itself. The transmitter sends a signal to the receiver, which tells the toy what to do. The receiver then sends a signal back to the transmitter, telling the operator what the toy is doing. This allows the operator to control the toy from a distance.

The transmitter and receiver use a specific frequency to communicate with each other. This frequency is chosen so that it will not interfere with other devices, such as other RC toys or garage door openers. The transmitter and receiver also use a code to transmit and receive signals. This code ensures that the toy only responds to the transmitter that is controlling it.

The range of an RC toy depends on the power of the transmitter and the sensitivity of the receiver. The range can be as short as a few feet or as long as several miles. Some RC toys have a built-in antenna, while others require an external antenna. An external antenna can improve the range of the toy.

RC toys come in a variety of shapes and sizes. Some of the most popular RC toys include cars, trucks, boats, airplanes, and helicopters. RC toys can be a lot of fun for people of all ages. They can be used for racing, stunts, and just plain fun.
