iam working on the project infrared remote control car.i completed it by running the car in forward as well as reverse direction .
i modified in this circuit that after cd4017 ic i take 2 outputs and fed to L293D ic to drive motor instead of a transistorBD139 driving a motor here.
so,when i press a button(any on t.v.remote it moves forward and for next pulse stops .during next pulse it will go in reverse direction).
but ,still i have a problem.i want to use t.v.remote to send ir signals in such a way that whenever i press program up/down button it should move forward/reverse and it should move left/right when i press volume up/down.should i go for microcontroller or anyother possible ways?

 

A microcontroller would be the easiest solution. You have to decode the ir signal to know whether up or down was pressed.

 

Why not get an old TV and use the IR receiver from it. Sometimes you can be lucky and they will be on their own small board other wise you may have to cut it out of the main TV PCB.
