I think that this tutorial helped me the most, because when I first got the NRF24L01 I was like really sad cause I couldn't transmit data, couldn't change the constant chars of course, but now I understood that I need to transmit a char multiple times forming a kind of period of seconds per every transmit. So that I can control the period with some input from the joystick and transmit it to the receiver which can detect the period and then do whatever I want with it. Thank you a lot!
I made one last month for my end study project using your previous method, this video will help me to update Some issues. thanks a lot my friend. by the way i'll came to visit Barcelona in next summer i hope meeting you there.
I bought my items from Aliexpress, cause it's a very cheep: "Digital LED Capacity Tester Battery Indicator", good joysticks, and NRF24l01 module with "AMS1117 Socket Adapter Plate Board For 8Pin NRF24L01". All those cost me about 45 dollars with 3d printed case.
I really appreciate the way you communicate information without lot of filler and always inserting little bits of wisdom...watch out for this...careful to do that. You are passing so much information, I find myself having to pause. I'm grateful that you share this knowledge and I'm interested in the PCB item you mentioned...when I get good.
The transmit loop() at time 13:20 shows all the input signals being assigned to the channel 1 of the transmitted structure. Looks like a copy-paste error!
I've ben trying to get these nrf24 modules to work for days now i was about to just desolder the sma connectors and throw em away then i stumbled across your tutorial and they work first try thanks so much
Hello Sir, thanks for this tutorial but you have some small error in your transmitter code. You mapped from 0-1024 to 0-255. I think it should have been mapping from 0-1023 into 0-255.
I am happy that you reply my comment so that why i deleted that comment. Keep it up bro.😊😊😊😊.I gave that comment because you not replied me in form. So i thought that you are not seeing any comments.
Hi, I'm thinking of making a simple two channel rc plane that steers using differential thrust. Will the transmitter and reciever be as complicated as shown in the video or is there a simpler way to build it using only a few of the components in the video?
In the loop function you have all inputs being assigned to ch1 at one point, fixed later on, small copy/paste error I guess that was remedied during debug. Otherwise very good, thanks!!
Hello Electronoobs. I saw that you used two types of capacitors, but at the schematics i can only see one of then. At receiver is ok, but where do I connect the small capacitor at transmitter? Thank you.
7:05...for future projects can u make just a gyro controlled transmitter with a small board without the toggle switches and joysticks? Please consider this! :)
Amazing work and dedication !! would love to see how to add the mpu6050 and get the yaw without drifting, That's gonna be super informative, I really liked how you explained the Code!
Very good design! Thanks a lot. Both me and my friend build the transmitter and receiver. During the test with the potentiometer on channel 0 we observed the same error. Intermittend channel 2,3 and 4 showed the full width for 1 or 2 runs and channel 1 jumped to the nul position. We see this on 2 different builds of the project. The systems are 250km away from each other. I think when this shows up when the drone is in the air something nasty will happen. Did someone of you see this problem as well?
I tried the test codes but the value in my serial monitor in my potentiometer did not change , checked the connections and even all my things are brand new and from a reputated seller , what might be the problem
The nrf24l01+ are great modules, I managed to test the communication between two with 2dbi antena and get a range of over 400m(that was the space I could walk before getting borred) it matters the position of the antennas it's a minus of this kind of whip antenna but still usable. Regarding the code we don't actually need to make it as the commercial ones, for example servos and esc can be controlled with the servo library and you can use the nrf to make a 2way communication and send some sensor values back to the remote. Offtopic... I got a microOSD based on atmega328p and a max7456 which I want to use for video overlay but I want to use my own way to make the connection between board and not use the MAVLink protocol, I have no schematic for the microOSD... do you have any ideas how could be done?
For receiver part, I want to use NodeMcu esp8266 v3. I wired accordingly but the output value is showing 1498 only irrespective of transmitter pot position. please help!!!
I love your tutorials! Small thing that did not work for me is that my modules were too close togheter and could not make them work. Took them 1m away from each other everything started working fine.
In just realized, in the schematic for the receiver, 5V from ESC is being supplied directly to 5V on Arduino. But the problem is that most ESC supplies between 5 - 6V, in my case I have one that supply 5.7V, so in that case wouldn't 5.7V fry the micro-controller on Arduino? Should I use Vin pin on Arduino instead?
When I use the same code and setup, my ESC just beeps and nothing works, without the ESC all the servos work fine, there is just no throttle. Any idea why?

Would you mind elaborating, i dont quite understand?
Finally I understood RF modules communication .Simply effective tutorial ❤
Finally found it a year later congratulations you just gained a subscriber
Really awesome work, man. That and a 3d printed case could be awesome! 😀
Tell me how to connect plz
@@chakriyatech2364 What exactly do you mean? :)
I saw in the comments, that you helped many people with this tutorial!!! & Me too!
Soo helpful!!! Love your tips!!! Best YT video about NRF24 and Arduino!
Thank you for reminding me that I have some NRF modules that I need to do something with.
I sense a future project coming soon...
thank you. I always share your videos with my university friends.
nice
Some of the best videos on the tube….very well put together. Thank you!
Your videos are really top notch man! I hope you keep up the good work! Lately I have been hitting your website very first to learn new stuff!

Nice video as always 👌 my girlfriend already knows you by your voice when i’m watching your videos :D
hahaha... mine would too ... hahaha ... but i don't have any friends ... hahaha
I have been wanting this tutorial for sooooo long!
Immediately subscribed :) and LIKED

Yes. Don't worry, that's just in the video. A small mistake. In the code is from Ch1 to Ch7. Keep up and thank you!

Thank you sooooo much my friend i have been vaiting for this for sooooo long now i can build a drone or a rc plane
I have made a same to same working prototype on perfboard ....
worked like a charm using ur codes .......
I really like your step by step explanation of the code.Thank you so much!
Thanks electronicnoob that is perfactly working yesterday i have completed controller or receiver..
Hello Sir, thanks for this tutorial but you have some small error in your transmitter code. You mapped from 0-1024 to 0-255. I think it should have been mapping from 0-1023 into 0-255.
I got the problem.. By coping his code 😅
That doesn't matter if you map from 1023 or 1024 the maximum will be 255 if value overflows and minimum will be 0 if value goes in negative.
@@rameshwargadekar7626not really, you will reach 255 before the potentiometer comes to the end . I think idk lol

Thank you for this. I'm going to give it a try and go for the pro build.
At 12:32 the send.data lines should be from ch1 to ch7. That's an error in the video. If you download the code, the error won't be there. Keep up!
Electronoobs 程序在哪里
Thanks for the tutorial. I have successfully build my Transmitter and reciever using this codes.
por favor me puedes ayudar con la capacidad del potenciometro
BJB oh
hi , m beginer with this project , can you design pcb with more simplicity and Arduino nano pro mini and Arduino nano,
Nice work really appreciated, have seen many videos but only yours cleared my doubt👍
Happy to hear that! Thanks!
In the loop function you have all inputs being assigned to ch1 at one point, fixed later on, small copy/paste error I guess that was remedied during debug. Otherwise very good, thanks!!
Grumpy Old Tech yes. Other subscribers told me that. My mistake. Just in the video. The code that you download has ch1 to ch7. Keep up!
Thank you for everything you said ! You helped me a lot figuring how i was going to do it !
I'm thankful for your videos its working n i have made my NRF transmitter and receiver
Hello Electronoobs. I saw that you used two types of capacitors, but at the schematics i can only see one of then. At receiver is ok, but where do I connect the small capacitor at transmitter? Thank you.
Your tutorial are simply fantastic ! You are great ! Thank you so much !
this helped me a ton with a school project, ty man
Incredibly well explained and helpful video. Thank you for sharing your knowledge.

Thank you Sir, it really helped alot to clear almost all my Doubts
Thanks a Bunch
Nice! Ive been looking for a video on exactly This!
this is the best video in the whole youtube . I am very thankful to you . you helped me a lot . thanksssssssssssss A lotttttttttttttttttt
Keep up with the awesome video. I need this video today, veryy helpful and have recommended to friends. Thank you!!!:)
In time 12:57 in void loop struct send_data.ch1 .... and ch2 ? ch3 ? I only see one channel on the loop !!!! 😐
is that a 104 orange Ceramic Capacitor ? 7:56 if so what voltage to get?
which Ceramic Capacitor (voltage)?
Amazing work and dedication !! would love to see how to add the mpu6050 and get the yaw without drifting, That's gonna be super informative, I really liked how you explained the Code!
nice work keep it up. this was really helpful in understanding RF working.
ive yet to do this but i think you explained the subject clearly and succint thanks
You deserve a salute bro..... keep it up.
Thanks for the great info man
I can not download code test receiver and transmitter. Your videos are well explained. Excellent.
Thank you very much!
Your content is always helpful.
First of all awesome video and what I have an idea is please make a video on how to make a FM transmitter
very nice NRF24 video!!!
Very good design! Thanks a lot. Both me and my friend build the transmitter and receiver.

Did someone of you see this problem as well?
Nope sorry mine work fine
This is freaking brilliant. Thanks a ton.
Finally I have made this project... Its work great .thanks
MUSTAQUE AHMED how much distance signal can cover?
Nice project! Very clean code!
I tried the test codes but the value in my serial monitor in my potentiometer did not change , checked the connections and even all my things are brand new and from a reputated seller , what might be the problem
For getting rid of the noise... Wrap aluminium foild around the data wire and connect the foil to ground.
Thank you so much .I assembled this circuit in last week. it was working very well (perfect) when until i broke my arduino nano😂😂😂.
What potionmeter u using man
great explanation bro
Was really helpful! I made it and it is successful. Thanks sir!!!
Very good explanation of your code. Thank you
thank for all, Bro....it is very good for me
I love ELECTRONOOBS
The outputs D2, D4 and D7 are not PWM outputs, how will the pulses be generated?
I am really impressed! Thank you for very nice tutorial.

The receiver keeps showing 1498 , I checked all the connections , they were ok , What's the problem?
You're the best bro,its help a lot 😍😍
please help me, how to send the String between two nrf24 module. !,
How to connect esc for brushless motor to channel 1 and 2 and set throttle
Maan you are an artistronic , Thaaanks a lot !!!
can I use this
transmitter for your brushed drone project ????
+1
Great vid sir well done I’ve learned so much from you , 👍🏻🇬🇧
That's just what I wanted. Thanks a lot
Can I use only the main 4 channels with the same code??
What about its range
Can I use it for rc airplane
amizing thank you teacher i hope done more for electronique
from algeria north africa
Awesome episode thank you so much 😀
bro 13:10, all values are going to ch1??
No, just a video mistake. In the code that you download are from ch1 to ch7. Keep up!
man, you're the best!
very nice work, I suggest you a similar project: build an rf controller dedicated to parrot toy drones, it could be a very nice deal...
Great work. Hoping you could help me understand how you have analog inputs, but digital outputs for those analog inputs? Thanks.
Hats off. Best explanation of the code ever. Thank you so much.

Amazing tutorial 😊👍
great video! I want to reduce the size of the receiver as I am trying to build it for 1:64 rc car
can i use two different types of arduino, arduino uno as receiver and arduino nano as transmiter?
Yes but check for pins of pwm, and miso meso etc
We can use this transmitter and receivers for quadcopter
Can you make a 3d printed case for the controller 15:45?
Bro u are my fallen angel bro thank u very much
Congratulations, nice project, thanks for share.
Hi friend
Perfect! But if the mix of channels was added, it would be very complete
