RF Communication

I am using an RF transmitter and receiver at a frequency of 315 mhz. I just want to know if you need an encoder and decoder to transmit instructions like if button1 is pressed motor1 will rotate forward or something?

Yes. Use the VirtualWire or RadioHead libraries. Get the examples working first before adding motor controls, etc.

Depends on your module. Did the setup come with 2262/2272 chips?

No idea, you haven’t told us which TX and RX modules you have. We don’t read your mind!
