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..

The graphics you use is amazing made
Thanks mate 👍
Thanks for update
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
You can create a mesh and use few as repeaters
I was losing my mind trying to figure this out, until I came across this video. I watched alot of old video and none of them helped
Hope I was able to help you
@@CrazyCoupleDIY You did. I solved the problem after watching your video
It's a pleasure
You explained this very well. Thank you
Pleasure
Bitcoin is my life
I am going to watch your other video now
Great explanation i had ever seen, when can we see Mesh Tutorial
This is such a good video. Thank you so much!!
Glad it was helpful!

This is the only detailed video I could find, thank you!

How to updating value here text1[] and text2[] using push button.
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
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
This setup works very well. I'm using arduino pro micro and NRF24L01 power adapter and everything works as expected. Thank you very much! 😃
Pleasure to help

Thought I'd never get these modules to work until i found your post. You explain everything so well. Thank you so much....
Pleasure mate 👍
excellent video! trust me i watched a lot coz i am a noob trying to solve a practical problem
Cheers mate
@@CrazyCoupleDIY wondering if you can make NRF24L01 display remote temp data on a TTGO ESP32
keep it up.....great explain i had ever seen
Thanks mate 👍
Amazing and clear tutorial
Glad it was helpful!
Very nice bhaiya
Brother loved your work, this video helped me a lot...Thanyou Very Much
It's am absolute pleasure 🙏
For 5:34 what does "SS" refere to?
Pin D10 of arduino nano is SS or Slave Select Pin
Pin D10 of arduino nano is SS or Slave Select Pin
The address can be 3-5 bytes long. Look at the chip documentation.
That is correct
I want to setup one transmitter to many receivers. How many receivers can one transmitter handle?
8
"bloody hell!" 😂 Great video, greetings from England.
Glad you enjoyed!
Hello Sir, where is the code 4 for multiceiver network? I really need it
I haven't finished the video yet
Will upload once done
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?
This is great mate
Thanks
The explanation is clear, thanks
Pleasure
Sir iam from the uk iam a teacher in college me and my students watch. Your channel once a week, we love ❤️ your vids thank you sir my students have a few questions for you it would be a honour if you could advise them
Your explanation is nice. Thanx
You are most welcome
Did you do a follow up video about how to set up the multiceiver network?
Not yet
But will do one soon
@@CrazyCoupleDIYI’m waiting patiently as well! This one was so helpful.
On its way
May be after few videos
Thank you for this very usefull tutorial, just one question : can you please tell me what is the value of the two resistors that you used in combination with the two pushbuttons ?
100 ohms
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
Hello Sir, where is the multiceiver video? I really need it
Will upload soon
@@CrazyCoupleDIY when you will upload the video, I can't wait to try it
Stay tuned, soon I will
Great video!
Thanks
Thank you
You are welcome
This is a really great tutorial, thanks!
Glad it was helpful!
Hmm, you using 10 byte of an address,but it really only supports 5 bytes.
You are correct, that's my bad
@Crazy Couple DIY Thank you for confirming.
These god-forsaken radio modules are even more sensitive than my girlfriend. Such an attention seeking piece of hardware. 🥲
Thanks for the great video.
Ha ha ha
