Thank you for the great video....
I need your help.....
Can you help me control 4 servo motors using 4 potentiometer.....
wirelessly.....NRFL01.....please,......
And the code explaination alsoo....
And is HC-12 better than NRFl01 for this...?
But can it switch between receiver and transmitter mid-program?
@@yuridanylko yes pls see it on how to mechatronics

well finaly someone explaining what line in code does what, most of those tutorials are "copy paste my setup and learn yourself with no clue". good job
Thank you! An excellent and logically presented tutorial. Has inspired me to start my own experiments.
Thankyou Sir for such a clear, concise and easy to understand tutorial. You covered so many aspects which I was not sure about and have undoubtably saved me a lot of time and expense.
Great video man! Good and fast introduction to these modules. New sub!
very good video with clear cut explaination. Good job, keep it up.
Couldn't be better, thank you. Excellent tutorial and explanation.
Have watched this video several times now, referencing the information. Great video!
Man, thank you very much! From Kazakhstan) in russian youtube i haven't find so clear and clean video
This code serves as a basic outline for anyone to modify it to their needs. Great job
Very clear and clean video. Thank you
works 100%...as i didnt have the buzzer, so i replaced my code for led blinking to show that data is still being received by the receiver. Awesome and thanks!
Thanks for that vert well made tutorial and code explain about the nrf24 modules, you saved my life, almost for now haha thank you very much dude
thanks, bro, I finally got a smile on my face.
keep making these videoes, all the best for monetization.
Sir please tell what is the final range of the nrf24l01 modul
@@bagavathi9428 it's 1070 meters in ideal conditions, although I've seen a few tutorials where they avoid using long wires, and wrap the ground cable with the mosi and miso in order to gain a few meters
Hi - what data speeds were you using for the range test please? (I see fastest 2Mb knocks back RX sensitivity a lot). I have also subscribed as it is a really good, clear video.
Very well presented. Thank you!
Thank you very much!!!! Unlike others, this video was very helpful and extremely easy to follow!! I have a quick question, if you don't mind. When you performed the range test how did you power the units? Were you connected to a laptop or did you use a battery power source, if so what did you use?
Thank you again for taking the time to make this great video
Thanks for your comments. I powered arduino boards with classic power banks, one is ravpower 16000mah, the other some chinese 5600mah. Also I did not work with HC-12modules so cannot comment on that. My primary use for this was controler for heating (thermostat in living room and controler in basement). But I ended up using nodeMCU because its all in the house and i use wifi. Its much simpler and if range is not priority, much more flexible because of webserver.
Tehno Manik wow thats a lot of current, did you feel that much current was needed? I was planning on using 2 - 3.7 4000mah 18650 in series, do think thats enough or will it be drained quickly. Sorry I cant find any datasheets on this module..
I have not tested current consumption, but if I remmeber it will drain about 200ma when transmiting, so depending on your setup and requirements i would say that 4000ma would be enough for at least 15h of transmitting. Of course, this is constant transmission, if you transmit periodically for second or two it would last much longer.
Tehno Manik again thank you for your time and efforts to help others, I truly appreciate you!!
Hello Tehno Manik,
Thank you for a great video.
EXCELENT BRO.. YOU ARE VERY SMART.. THANK YOU VERY MUCH AND CONGRATULATION...
Thank you so much sir. I absolutely understand and I tried it with the help of your vedio.
Thanks a lots sir.
Top Video and easy to follow you!
Well done!
Excellent tutorial, i learn a lot. Thank you
Thanks for the video. It was quite informative and well done.
Very good tutorial. Well explained code unlike in other tutorials on youtube
Thank you for your comment and support. Cheers!
Thanks a lot man. It has really been a big help.
this worked great thanks for your contributions sir!
Great video. Good explanation.. Keep the videos coming. You have a new sub
Thanks so much for the amazing tutorial! I finally got my NRF24 working!
Bro can u help me to make a controller and receiver for 8 channel with nrf24
Good instructions.
It would be useful to attach a reference to the library (). Not everyone has everything installed. To write "nRF24L01.h"
Super Helpful Tutorial!! Thank you very much! 👍👍👍
Also I forgot to ask, do you have experience with the HC-12 modules? If so, will you share your experience and also will you make a comparison video, please?
Perfekt video and explanation. Thank you very much
This is a really good video. Good job, and thank you.
Thanks alot! You are very good at explaining. Subscribed! 👍
Good video ...it was clear and neat . thanks for the video
hello good video, do you have any video with the MQ-135 sensor with this antenna?
Is there a way to pair rc receiver to arduino transmitter, I want an rc receiver because of how compact and cheap it is and also the wide voltage range I can input to it
Kudos - Very well done.
My name is Mahamad. I am from Malaysia. Your video is simple and easy to understand. I am very interested in using the NRF 24L01 as voice transmitter and video transmitter. But I dont know how to program it. Can the source code you give work with the arduino nano /mini pro and uno base ? Thank you very much for your effort to make such a good video for International / global audiance .
this is the best tutorial about NRF24l01
Best tutorial ever !
Thank you for the video it has helped me on my project. What software did you use to test the range?
It looks like Google earth. If you know the location of the transmitter, keep that in mind and drive with the receiver until it looses signal, then map it on Google earth
Mega useful thanks buddy new subscriber.
Very good video, thanks man!
thankyou very much Sir, it was really alot helpful in clearing my some misconceptions.
Very concise, I like the this makes it work here you go, run with it.
Well presented. Thanks from Indonesia
Se eu tiver esse adaptador não preciso colocar o capacitor entre o VCC e GND?
Nice job, impressive range for 2.4 GHz, considering Bluetooth and 802.11 LAN reach 100m. Any idea why the range with NRF24 is greater?
BT devices generally have small internal antennas, and also have high bandwidth. With WiFi using 24dbi directional antennas you can get several kilometers range (tested about 3km with line of sight). As in any rf communication, better antenna and higher power means greater range. Also higher bandwith means less range (for eg 4G mobile network vs 2G GPRS).
I'm designing a yegi antenna for nrf24l01 modules! How much renge will we get? What you think?
I tested them up to a distance of 1500m @250kbps channel 100 (2.500 GHz). At this high frequency there is no interference from wifi!
I will test it bro, sounds pretty good for my proyect of 10km data sending
So I followed the same setup in the video with same hardware and same code. Yet the buzzer goes off constantly instead of at intervals, and it does this whether or not the receiver is off. I've tried a different tutorial and still nothing works. Any ideas of what may be wrong?
muito bom, vc teria um exemplo bidirecional (tranceiver)
?
Hi.. Im having trouble with my project. Using 2 arduino , I want to make a traffic control system with red and green LED which will light up if the Ultrasonic sensor detect an object (car). I want the system to work wireless using nrf24l01. When the first green LED turn on(for 1 min), the second green LED on the other arduino should turn off (red is on) even if its Ultrasonic sensor detect an object. It can only turn green after 5 second the first red LED turn on while the green was off. Can u help me with the program?
Thank you very much, you helped me a lot
Thanks a lot, with this video I could did a behavior test and I could saw a perfect behavior with my modules. thank you !! another thing, you know how send analog values with these modules, for example send potentiometer values or a some temp sensor values? regards!
Glad you like the video, thanks for comment. As for sending values, you can cast it to char array on the transmitting unit and send it to receiver. Than on receiver end if needed cast it back to numerical type (int or float) so you can use it in your calculations.
great video, is it possible to send video signal with this system?
Good video tutorial!
It eliminated many doubts of mine. Easy to understand. I understood even though I didn't know English.
Congratulations and thank you very much!
I'm César Augusto Becker from Brazil.
What is the min distance between the transmitter and reciever to test the units are working?
Hi, I would like to know if the NRF24L01 with antenna can work without Base Module?
Thanks for Your tutorial. For today I had a problem to connect nrf24l01with UNO. ;-)
Do you still need adapter if you're going to connect NRF to NodeMCU or ESP32 which has 3.3v output?
Hi I had a little question do you think it works if we control it from home knowing that I control it from a lap of about 40 m and that the receiver is still in motion at 20 cm from the ground In the middle of town?
Just purchased a pair of these on Amazon. But, I want to use them with ESP32/8266 MCUs and RPi Compute Modules, preferably with Python and/or microPython. But, I'm not finding much info nor YT videos on these configurations. Only Arduino & IDE.🤔
Thanks for this excellent video...
Excelente vídeo, muchas gracias por compartir.
Me costo un poco, mi ingles es muy malo, pero algo entendí.
Saludos cordiales desde Perú.
THANK YOU VERY MUCH NICE VIDOE HOPE YOU DO MORE.
What specific base module you are talking about, can't find them online
A Very good video
Very Clear Tutorial Thanks
*THANK YOU SO MUCH* ....Your video tutorial helped me a lot and I'm so happy that I can't explain in word. Thank You Thank You so much ......
Thank you sir, working fine
nice job, what is the maximum frequency we can transmit between tow module NRF24L01
It has 125 channels with 1Mhz step between each other and starting at 2400Mhz, so it would work up to 2525Mhz
Very cool tutorial
Thank you nice video. Was very good explained, y had errors before i now why now
Your code works with the standard nrf24l01 but not with NRF24L01+PA+LNA SMA Wireless Antenna Transceiver. What am I missing here? Or maybe the NRF24L01+PA+LNA SMA set I bought is faulty!!
Same with me, someone please help
Excelente vídeo
How can you add someting in your transmitted data like 2 float variables ?
hii...i've successed using nrf24 with internal antena, but when i try to using nrf24 with external antena, function isChipConnected( ) always return false / zero. what should i do?
Which capacitor value we use
your the best ...really good video very clear ,thanks

Can i transmit video data with these modules ??
What are the method that you used while you measure the range of nRF, are you use GPS Module?, Thank You
Google maps.
Hello! I have an arduino uno and an arduino nano. I have uploaded the code of transmitter in arduino uno and for the receiver in arduino nano (in different pins) nd instead of a buzzer i placed a led ,but it doesnt work. Why is that happening? Thank you in advance!
This is what i need! What the code does instead of copy and paste. I wanna use it for my projects and easily add it. Thanks 🙏
Thanks it is a very useful video, nice 😊😊
Hi sir,
Great video
what is changes we have to do replace uno with nano please suggest any material.
Never tried nano, but it should be same code, only thing you have to change is your device in Arduino IDE for compiling and upload. Also I'm not sure about voltage on nano pins, uno has 5V outputs, if nano is 3.3V maybe you will need to use voltage level shifter from 3.3V to 5V. Cheers!
If we put the transmitter inside a house, and put the receiver outside, theoretically how much range can we get?
thanks man !!!
Can Bluetooth signals be detected and a ring is emitted when detected by these electronic parts?
keep it up bro....👌👌👍
Somebody help me, We only defined the CE and CSN pin of the NRF24lo1 to the arduino in the code, what happened to the rest of the three NRF24l01 pins ( SCK, MOSI, MISO) in the code, or it dosent matter to the code ! so we could randomly connect these pins to any digital pins in arduino differently in transmitter and receiver ?
The atmega328 chip has predefined pins for SCK, MOSI, and MISO as digital pins 13, 11, and 12 respectively. The chip select pin can be any digital pin, pulling low to to enable the communication, as per the SPI documentation.
How does datarate affect range? 250kbps vs 1Mbps vs 2Mbps
my buzzer doesn't delay, it's just a solid tone. Even when only the receiver is powered .
Anyone have any idea why>
Thank you for this video! Using your script and tutorial I was able to make a transmitter with a Nano. However the transmitter only worked when the Nano was plugged into a USB cord. A separate 6.6 volt battery input to VIN and GND would not let the transmitter work. Not sure why yet.
Maybe battery doesn't have enough power (miliamps) to drive module when transmitting. When using USB power it goes through regulator and I'm not sure if regulator also has capacitors in the circuit which helps stabilize voltage and power draw. I never used VIN to power my devices so cannot comment in more detail.
@@TehnoManik The battery is a 6.6 volt LiFe rated at 5C, so in theory it's capable of putting out 33 amps. Therefore I don't think the battery is the issue. The RF modules are plugged into module adapters, which are plugged into the 5 volt output from the Nano. The adapters have capacitor filtering and are regulated to 3.3 volts for the RF module. Time to do some further digging.
OOPS! Typo. 6.6 volts, 700 mah at 5C would be 3.5 amps. Still plenty of power to do the job.
Not sure what to say, never powered arduino boards with VIN, only USB. Datasheet says 7-12V power input for board, maybe 6.6V is too low with voltage drop when module is transmitting. You can try to power module directly from battery, not through arduino pins. Look for connection diagrams online, just remember to ground everything together.
@@TehnoManik Yep, after some further research on the Nano, the 5V pin is fed directly from the USB 5V power.....or through a 5V regulator from the VIN pin with VIN from 7-20 volts.....or it can be used as a direct 5V input. The 6.6 volt input to VIN isn't enough to maintain 5 volts under a load due to the voltage drop of the regulator, not the battery. Lesson learned.
How did you investigate the data loss?
Good video. I have two of the high power modules but I can't get them to work. I set them up using the 3.3V outlet on each arduino for each module. After watching your video I see that this might be my issue. When I run the code to send a message from one arduino to the other all I get are blank messages on the other side. Is there anything else I could try or should I buy the base modules? Thanks.
@Dublin In the end I just used the short range modules that worked fine for me. Only thing I can think of is to make sure your send and receive baud rate in the serial monitors are the same.
Bro my modules are not communicating even i used different ones... I worked very hard but nothing came in my favour... Please help me... is it due to absence of base adaptors
Hi Bro, the base module is compulsory? i am doing a project but no use the based module too.
Yes base module is must have for stable operation because during transmitting arduino cannot deliver enough amps for successful transmission, hence base module with built in capacitors to store extra power when needed.
thanks
what is the name of the base module
good Job gentleman hope your are continue :)
