arduino to arduino wireless communication

You can use anly one tramitter and 5 receiver that all receive the same signal in a single channel and at the end of each receiver an arduino (as shabaz say) or you  can also use an attiny that is less expensive than an atmega 328. To transmitt data you can divide your packet into two pieces: an header with a code that specify what servo you are controlling and the data piece thet you can use to trasmitt a number that means the position that the servo have to reach, the microcontroller at the receiver only translate the data if the header that receive is correct so you can control all servos using a single channel.

Hope that this will help.

I am just a beginner, and  this idea sound amazing,

i would be grateful if i could get some more information on how i can do this, and will i be able to control all servos simultaneously?

First of all the 5 servos that you want to control are far from each other? If no you can use only a single transmitter/receiver couple and a single microcontroller as receiver so your project can also be less expensive, the "receiver microcontroller" then will control the proper servo using the same method that I have explained you before.

With this method you can't control servos "really simultaneously" because if you're transmitting the data packet to move one servo of course you aren't controlling the other 4 servos, however the time that you spend for a single transmission is really short so you can't physically see this kind of delay and you will see that all servos will respond real time to your commands.

You can transmit data basically in two way:

-a loop where you transmit first the data for the first servo, then the same for the second, the third ecc... this is a kind of polling

-you transmit data at the proper servo only if its position have to change, this method probably it's a bit more elaborate but allow at your microcontroller to do something else if you haven't to change servos position.

As Shabaz suggested, try to do one small step at the time: for example you can make first the receiver system for only one servo and try it with serial monitor (so you haven't the problem of wireless communication), once it work you can make the whole transmitter/receiver system with only one servo and then extend for all 5 servos, you have to try just a thing at the time and make sure that it works.

When all works you can also add something cool and personal at this project, for example a special command that move all servos simultaneously instead of only one, trying make something new is the best way to learn

Thank you,
