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?

micro controller will be the only solution. it s not complicated . i have the same project in my site check it
 
hey can u help me....i made ir car wid d same ckt as u hav....but d counter is not reseting....it just turns on but doesn't resets itself....i hav to unplug d power supply den only it resets....can u help me out.....is dere any additional ckt to b added plzzz tell me......

MOD : What language is this??
Using short hand typing / sms language is not allowed in this forum, and expect you to correct it on your next login. Else be ready for an Infraction
 

For 4 channel IR remote, use simple IC based ciruits HT12A as encoder and HT12 as decoder. Application cicruits will be available on the device datasheet.
 

you have to go through the datasheet of cd4017
in which pin no 15 is used for reset .
