All About nRF24L01 Modules

PCBway: only $5 for 10 pcbs from www.pcbway.com...
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..

thanks mate! the vid has some insane quality compared to the other videos and it ACTUALLY tells us what the NRF24L01 is, currently in a competitive high school level UAV team, and responsible for the RC, which is gonna be powered by Arduino, which leads to NRF2

I am so happy so help you, mate. Thanks for your kind words

Thought I'd never get these modules to work until i found your post. You explain everything so well. Thank you so much....

A smashing tutorial. The bidirectional tutorial 7:57 was the most useful for my project - a remote timed rain gauge data exchange. Thank you, I will send a "Super Thanks $" later this year.

[@CrazyCoupleDIY]

Glad it helped! And thanks a lot

Salute for this video... I have one doubt If my transmitter is in 3rd floor and my received in ground floor in between some wall 🧱 then it will work? If not then what will be the solution for this...please tell me

[@CrazyCoupleDIY]

You can create a mesh and use few as repeaters

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?

Did you do a follow up video about how to set up the multiceiver network?

Not yet But will do one soon

@@CrazyCoupleDIY wondering if you can make NRF24L01 display remote temp data on a TTGO ESP32

[@abhi143singh1]

Hi, i had seen your video & its useful. i had used it as transreceiver some data packet sent from transmitter to receiver & from receiver to transmitter. I got range but the latency is not good enough. I need realtime operation like switch i.e. latency required less than 20ms. Can you suggest what to do

[@CrazyCoupleDIY]

I haven't used this sensor for critical stuff yet. Hence, latency has never been an issue for me. 1. I use this sensor at my doorbell 2. Created a shooting game similar to laser tags

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....

[@CrazyCoupleDIY]

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

[@digihz_data]

Hmm, you using 10 byte of an address,but it really only supports 5 bytes.

[@CrazyCoupleDIY]

You are correct, that's my bad
