[SOLVED] rf remote controlled car

[shahare.sumedh]

i have some RF circuit diagrams,, i am going to connect my circuit in the same manner ,, as given in the diagrams it should work,,, will it work,,
will rf transmitter FS1000A work with ht12e.
please help me...

definetely it will work 100 %. Need to do proper coding. this is already implemented and tested by me.:grin:

thanks dude...
proper coding means what??
is it connecting the 4 pins of ht12e to ground as required..

Yes you are right. The transmitter should transmit proper data so that the decoder gives correct input to L293D.
Example "A" is start car, "B" is left

"c" is right, D is reverse.
So it will be depending on the data you send.Ascii ot if the higher 4 bits will not change so you can ignore then and transmit only lower 4 nibbles.

Its example if you control through PC keyboard. if you use a remote then encode the data properly.
