Have a look at THIS article. It explains the circuits and gives a circuit for a wireless remote transmitter/reciever.

Thanks for that shumifan50, but the article does not explain how to control upto 16 receivers from just one transmitter remote control.

Could you please expand on this ?

Your question is akin to asking how do all the letters get delivered in my street when there is only one postman.

Simply speaking, the signal you send contains data. Part of that data is an address. In the simple case the address is the number of the station you wish to act on the message.

Maybe a big ask but...

Could someone possibly baby feed me a step by step guide as to how i would go about replicating the same device as shown above.

I.e.

Step 1- Purchase 16 fm receivers and 1 fm transmitter and 16 DC motors and batterys etc
Step 2- ........

To eventually achieve
A remote similar to the one shown that controls 16/+- Receivers at any 1 time
A receiver with a DC motor attached that turns only ON/OFF

Purchase:

17 Arduinos
17 NRF24L01 modules
16 relay shields
programming equipment
Various assorted components.

Then learn how to communicate with more than 6 modules at once (these modules have a feature that they can link to multiple other modules, but the magic number is 6).

Learn the Arduino environment.

Write some fairly simple code (It's C++, how hard can it be?)

All done, grab a beer.

(I may have left out some significant steps)

Also there are many options as to the microcontroller, the radio module, etc. This is just one of each as an example.

for more information about using these modules with an arduino, see here.

Practically, if I were makig this many I wouldn't use an actual arduino, I'd just use an ATMega328 chip (you need more than 8K of programming memory if you want to use the networking library, otherwise an ATMega8 might be OK).
