Re: How does my remote control car work?

I would like to know how my remote control car works, and 
how it knows when I am telling it to go forward, reverse, or 
turn.




Hello, Keith.



When you move the joystick, or press a button on your remote control, 
there are tiny buttons inside the control which you are pressing.  For 
example, the joystick usually has four buttons -- one for up, down, left 
and right.  With the permission of whoever owns it, you could take it apart 
to see them.  Moving the stick presses these buttons.  Then, there's a tiny 
computer in there which interprets the signal and sends it to the antenna 
on the remote control.



This antenna then sends the signal via a wave to the antenna on the car.  The 
car then has another small computer 
in it which interprets the signal from its antenna.  It then makes 
the car move or turn, depending on what the remote control told it to 
do.



I hope this has answered your question.  If you have any further questions,
