In my last tutorial I created a NodeMCU based Duino Coin Miner. It is an awesome little miner that sits on my desk and mines few cents a day.
However, adding these miners to my home network choked my WiFi router. Home Appliances and Smart Devices connected to the router constantly started dropping off. To my understanding, most of the wireless routers and access points can support upto 250 devices connected at once. So, what's happening here?
To clarify my doubts I called my ISP. The answer they gave was absolutely shocking. "ONLY 30 devices can successfully connect and exchange data via their router at any given time". Bloody hell!!
So, to overcome this limitation I added another router to the network to scale up the load.
But, I was not happy with this solution. So, I did a bit of research and found this "NRF24L01 RF Transceiver Module" which I can use to create a mesh of wirelessly connected microcontrollers.
In this tutorial, I am going to show you guys how to use this transceiver module to add wireless communication between two or more Arduino boards. I will be using this module for many of my upcoming home automation projects. Bang Problem solved..

Hey guys, mine NRF24L01 chips have M1 and M0 pins instead of MISO and MOSI pins. I thought they are the same, but the transmission doesn't work. Any ideas?

I write the program and upload it to the boards.... But hello world does not seen in the serial monitor... Is both the boards are connected in one lap or can I connect it with two other laptops??.... Led porgr also not working... Serial monitor shows something like "?>>?" This... I don't know where the problem is....

You can have them both on one laptop or on 2 separate ones. If you have them on one then use serial monitor for one and putty for the 2nd one. Please check id the baud rate is matching or not
