i some what understood your requirement u no need any external circuit b/w the processor and ht 12d/e
i think u r using this one for the RF RX/TX
only think u need is motor driver ckt b/w motor & processor
we r doing the same thing but not using ht12d/e
...cip8d/e it has 8 data line instead of 4
u can connect it directly processor & ht12d/e but note down active-low/high.....
