Need some help with wireless schematic

Currently trying to assist my son with a science fair project. Basically a robotic hand that basically moves up/down and left/right - sort of like the motion of a wrist. The goal is to make it wireless. The servos will be controlled by basically the same thing as a rc head tracker - you move your head and the "wrist" moves with it. We have made the headtracker using a nano and gyro board and uploaded the code we found online and it works great... according to the GUI interface that came with the code.

We found a rx/tx schematic (basically to control servos on rc plane with telemetry (which we don't need) on one of the rc forums, but the whole thing turned out sketchy... the code was in hex form and although I am ~ok with code, not very certain what was going on. Had a very tough time, and actually errors uploading the code onto a promini with cc2500 rx/tx module.

We would like to use something like a nano, and a tx/rx module that works well with it. Had no issues uploading code on the nano.

Can someone please help us moving along on this? Does anyone have a schematic for a wireless rx/tx module that basically controls up/down and left/right and maybe the ability to turn a light on/off by switch or push button on the tx unit?

I'm pretty good at following a schematic, but would need some help with code, or possibly code that already exists?

ANY help is GREATLY appreciated. My son is starting to get bummed out thinking we may not be able to accomplish his project goal. Thank you!!

A wireless module sends data. What data you have it send is irrelevant.

If you use XBees and appropriate shields, in place of wires, no code changes are needed.

There are cheaper radios available, if you need less throughput, less range, and less reliability.

All rely on sending serial data.

Thanks. I'm not really too sure I understand. Very new to all of this. Where do I find the receiver/transmitter? Also, you are saying I don't have to have code for any of this to work? Sorry for the stupid questions, trying to learn. Thanks.

Get whatever communications you need working with wires (using the TX/RX ports and GND) before considering wireless. Then the wireless step will be to replace the wires with suitable radio modules.
