I am concerned about logic. So the logic should go like this-
Whenever you press a button on transmitter circuit board particular data bits are produced. These data bits are then fed to the data pins of HT-12 encoder ic and then converted to serial data. That serial data is given to transmitter part of RF 434 module. This is done by connecting the data out pin of encoder ic to the data pin of transmitter.
Now the data is received by the receiver part of RF 434 module. The data pin of receiver part should be connected to the data in pin of HT-12 decoder ic. The data out pin of decoder ic gives the same data bits which are initially generated.
We have to program these data bits such that for a particular data bit motors of robot will run in a particular way so that say it moves in forward direction.
We just have to fed those data bits at the reciever side to arduino and code them accordingly.
Actually I’ve made this same project some time before using ATmega16 microcontroller IC and I used the same hardware components as mentioned above.
I hope this helps!
