RC, or radio control, refers to the technology that allows users to operate devices remotely using radio signals. This technology is commonly used in various applications, including RC cars, drones, and model airplanes. The user typically employs a handheld transmitter to send commands, which are received by a receiver in the device. The components of an RC system include the transmitter, receiver, and servos or motors that control the movement of the device. RC technology is popular among hobbyists and enthusiasts, providing a fun way to engage with electronics and engineering while enjoying outdoor activities.
