Everything is ready for project . I have one doubt! I am using transmitter + Arduino *Uno*..and receiver + arduino *nano* will it work?
Yes, it will work, in much the same way that you can send an email from a Mac to a Windows PC. The type of PC doesn't matter as long as they use the same protocol. As you haven't shared any details in that direction, I would say that if you have coded correctly, then it will work.
