به این متن و نحوه سوال و طرح این ماشین در حرکت و مشخص شدن حرکت به و سیله ال ی دی  دقت کنید. و البته به جواب سوال

First, thanks for your quick reply. And secondly, i am trying to build a "toy-car" remote system, having a forward, backward, leftward and rightward remote system as usual. And i would like to include another additional botton control for on and off for the head lamps. The forward and backward and the additional botton control for on and off for the head lamps control will be bottons (about 3 or 4), while the leftward and rightward will be controlled by tuning a varaible capacitor. I hope these discriptions of the "toy-car" remote system and receiver will help.Thank
