hardware section again there are two parts one is remote control and second is toycar. The remote control is joystic control of toycar which controls its motion in all the directions. Actually itís a four channel RF transmitter which generates four different codes and modulates it over 27 MHz carrier. In the toycar circuit there is RF receiver chip which demodulates and decodes these codes and drives two different motors one for forward and reverse motion and second for left & right turn. The remote control transmitter is connected with LPT port of computer and now the software will transmit the codes through this transmitter and it will move the toycar in desired direction. The same joystic control is given in the software also so that toycar will only move till the key (or mouse button) is pressed.
