Radio-controlled or remote-controlled toys, popularly called RC toys, are self-powered and can be controlled from a distance using a remote that works with radio waves.
1. When we push the control, the transmitter sends a specific number of electrical pulses corresponding to that action through the air. The transmitter has its own power source, usually in the form of a 9-volt battery. Without the battery, the transmitter will not be able to send the radiowaves to the receiver.

The remote control contains a radio transmitter which operates on a particular frequency that the receiver is designed to receive. Transmitter:
Receiver: The receiver is fixed within the car and constantly receives signals from the transmitter. When a transmission is identified, it translates the number of electrical pulses into action.
All remote control cars require a power source. Rechargeable batteries power small electric motors. Alternatively, some use small internal combustion engines. Power source:
Motor and Circuit Board: The motor is responsible for the turning motions of the toy while the circuit board works like a pool through which all commands go on to specific parts.
