How to make wireless robot car !!!!

Here,i m introduced wireless robo car using encoder(ht12e), decoder(ht12d) (ic) and RF modual  (433 MHz).here  i m using l298 dual full bridge driver ic .it having 1A current source  capability .
Now basic concept of wireless is  transmit the information through the transmitter and receive these information through  receiver  but  first  communicate with each other  synchronization is required  between transmitter and receiver so i m  using dip switch .through which i m adjust  the code same in both Tx and Rx.




here, i am give you  DPDT switch  configuration in remote control .

Now ,pin diagram of ht12e and ht12d ic   given below ,

click here to download HT12E datasheet

For HT12d ,

download HT12D ic datasheeet

Now ,main circuit diagram of transmitter and receiver circuit  is  given below .

Tx

Rx

 After implement your component in PCB  is look like

uhhhhhhh!!!   now  your  wireless robo car  ready to drive
Let's   go on long  car drive  with your  GF......:) enjoyyyyy...
