Wireless Communication Between Arduino Boards
I have multiple Arduino boards in my project, and I need them to communicate wirelessly. I've considered using RF modules, but I'm unsure about the most reliable and efficient way to establish communication between the boards. Can anyone share best practices or example code for establishing wireless communication between Arduino boards? Thank you!

Do you have any other requirement like range or power consumption? Depending on the requirements you can decide the approach for the problem
Well, the most used module is nrf24L01. You can make Arduino as the master and rest of the devices you are using as slaves. I think you can run up to 125 channels/125 devices by using nrf24L01.
Its frequency range is 2.4 to 2.5GHz and can transmit/receive in the speeds of 250Kbps, 1 Mbps, 2Mbps. If you are looking into power, it would consumer around 12mA during transmission. It uses SPI, so the system might get bulky if you are trying to connect all of them on the same board/close by.
There are plenty of online sources regarding this , you can follow any.
Here is one of them that might help you get started into browsing NRF24L01
