Taking the simplest case, say your car only moves forwards and backwards. For every command you send, you store the values in memory, and your car moves for a certain time for each.
When you send the repeat command, you read the values back from memory one by one and move accordingly.

Salem how to store in array using mplab...i just know using MPLAB..do you know how to write the command...tomorrow i send the assemble code to you then see whether you can modify it or not...thanks

Colin Mac ,i know what you mean store command in memory...i not sure izit use the PIC memory or use a IC memory and someone told me that PIC16F84A no enough memory space to store command..do you know how to write the command that can call out the instruction back from memory..

someone told me that PIC16F84A no enough memory space to store command.
According to the PIC16F84A data sheet, it has 68 bytes of general purpose RAM and 1K of program code.

Why is it someone would give you this project and expect it in a month if you have no experience in programming micros. If it's a school project, I think it's asking for much considering you have to design and build a remote controlled car at the same time.

[quote=Colin Mac;629099]PIC memory.
that's school project..i post the schematics of the remote control car.so can you check see got any problem in this circuit.i think my problem is don't know how to write the program to make it repeat the instruction without controlling.i just know write how to control the car using remote control but don't know how to write the program to repeat the same work.

There's no part no. shown for the RF transmitter module. The datasheet for the encoder shows it interfaced to a transmitter you must build. Are you building the transmitter yourself? The IC in your motor pic isn't an
LM2930. It looks like a H-bridge IC. You can get those with diodes built in.

ya..i'm wrong..is L293D for motor pic..izit the transmitter can buy in market but i think have many different types and frequency.if i want build it.. how..izit refer back the datasheet of PT2262 that i had attached the pic..actually i copy the schematics from senior..

i'm planning to use this website http://pro-radio.ru/user/uploads/126799.pdf on page 9 and place a PIC18F2525 between the RX and motor..The PIC will listen to the RX and pass what it hears/sees on to the motors.To record the PIC will also compress (more on that in another post) and record what it gets from the RX and still passes it on.
To playback the PIC reads the old commands from its memory and sends them on to the motors.
so now i think i need to learn another new language PIC C compiler
