Using Arduino Project Guidance

Hello, i was following this tutorial Home | Libre Mechanics – Open Knowledge on engineering development., and send messages between two arduinos using RF, but this only works if both transmitter and reciever are connected to USB port, can i send data without the TRANSMITTER connected to USB port ?

Thanks

Take the Serial.println out of the code and then it won't need the USB port. Power the devices some other way.
