Remote Control (RC) car transmitters are what allow people to control the movements of RC cars. Transmitters work by sending a signal from their antenna to the receiver of the RC car. This signal is then interpreted by the receiver and will cause different parts of the car to move according to the instructions sent via the transmitter.
The transmitter itself is powered by a battery and consists of several components. It has two sticks, one for controlling steering and one for controlling acceleration, as well as several buttons that can be used to control additional functions like lights or sound effects. The sticks are connected to potentiometers (variable resistors) which sense movement and send out varying electric signals.
These signals are then amplified and modulated so they can be transmitted via radio waves through an antenna on the transmitter. On the other end, inside the RC car, there is a receiver which picks up these radio waves, decodes them and sends out electric signals to different parts of the car.
These electric signals cause motors in different parts of the car to move in a certain way depending on what was sent from the transmitter. For example, if you press forward on the throttle stick, it will send an electric signal that tells a motor in one of the wheels to spin faster which will make your RC car accelerate.
Conclusion:
RC car transmitters work by sending out radio waves from their antenna which are picked up by a receiver inside an RC car. These radio waves carry instructions which cause motors in different parts of an RC Car to move in a certain way depending on how you manipulate sticks or buttons on your transmitter.
