hey folks, top of the day to you all, . . . .here's my problem
i have here, with me 2 dc motors operating on 24v dc, and i'm planning to inteface it with my arduino diecimila(atmega through an L293D h-bridge driving ic. which takes an input from the arduino(which is the output i trigger through my program to the respective ic pins) and drives the motor with a high current of upto 10 amps.

now, here's the real pain, . . . . . i have with me, an old rc car controller( the classic up,down || left,right) which through a lil bit of modification, i will transform into, a wired controller, whose outputs(viz. forward,reverse, left,right) i'll be assigning as inputs to my arduino.

now i dont really know where to put these inputs(analog or digital) and how to modify my program, or make a new program to accommodate these functions.

i want my bot to move :    front when i press forward
                                     reverse when i press backward
                                     turn left when i press front and left
                                      turn right when i press front and right
                                     reverse left when i press back and left
                                      reverse right when i press back and right
                                     take a 360 continuously left when i press only left
                                      take a 360 right continuously when i press only right


i'm using differential steering
and the functions described above (front, reverse etc) must me mandatorily present in my program. i want digital high or low to be triggered accordingly by analyzing my controller input(i.e front, back, left right)


i hope you folks can help me out. ..  .


thanks a damn!!!!
