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?
