Hello, its my first question to AAC (all about circuits) site really will thankful if get reply/solution to my question.

I am simply willing to design module in which i will be taking 3 Rx and 1 Tx. So i want to send a signal to 1st Transmitter at once when i will press the 1st push button interfaced with transmitter and LED connected at 1st transmitter will glow, similarly when press 2nd push button LED present at Receiver (2) will glow and so on.

I am not able to decide which module should i use to make this whether use RF module or other.

Thanks in advance.

Welcome to AAC!

It is not clear what you are asking.
What is the meaning of Rx and Tx?
Are you talking about Rx and Tx signal lines as in UART communications?
Or are Rx and Tx wireless modules?

In general, Rx means receiver and Tx means transmitter.
Rx cannot send to Tx.
Tx can send only. Rx can receive only.

Yes, Tx and Rx is meant by Transmitter and Receiver.

Yes, i would like to elaborate my question clearly.

I am simply willing to design module in which I will be taking 3 Receivers and single Transmitter. So I want to send a signal to 1st Receiver at a time when I will press the 1st push button which is interfaced with transmitter and after that LED connected at 1st Receiver will glow, similarly when press 2nd push button LED present at Receiver (2) will glow and so on.

All LED will not go at single go, but when the specific button is pressed which is allotted for specific receiver that Receiver's LED will glow to show that signal is received.

I am not able to decide which module should I use, to make this whether use RF module or other.

 

There are RF remote relay boards that will do just what you want. How many channels do you need. Up to 4 are quite common.

 

What is the maximum distance between the Tx and Rx?

Infra-red transmission is easy to implement. The distance limit is about 10 meters.

Distance is less than 100m, but is it possible to send signal to different receiver's at different time using single transmitter.

 

Distance is less than 100m, but is it possible to send signal to different receiver's at different time using single transmitter.

Yes. A single transmitter with three buttons can send commands to three separate receivers.

100m is pushing it but it can be done with the proper RF modules.

 

Yes. A single transmitter with three buttons can send commands to three separate receivers.

To be more specific, the transmitter sends the same signal to all three receivers, data bits tell which one it is intended for.

Do you really need 3 separate receivers? Are the physically separated such that that is necessary? Because one receiver can do the job.

Yes, I want to blow one led at one time after pressing button for receiver 1, and second time 2nd led for second receiver, and so on all are physically apart.

Okk, and how I have to assemble them to work at different data bits. Like am I need to code it or what?

Yes. Each receiver has to respond to a specific coded message. It does not have to be complicated. I could be as simple as different pulse length, different audio tone, or even a different radio frequency.

Thank you so much, for your help and time. Now I am good enough clear about idea, as experiments always face obstacles so if any problem I faces in future now I have powerful community I feel fortunate for that.
