NRF24L01 Drone Transmitter: How To Make Drone Control

[@KidsAnakStudio]

Good Job, brother. You did it so cleanly and clearly!

[@SmilingBeachHammock-my4qn]

yes! standard NRF24 drone transmitter, right? I see your updated github repo and you'll make upgraded NRF24 TX with 4 buttons. Waitiiing 😅

[@ArduJimmy]

Sure. I'm waiting for liPO battery and Shipping goes delay yesterday. The delay can be caused by 2025 activities. I dont know. some say overload shipping 😢

thanks. have a great saturday 👍

Sir i want to make a camera drone by using esp 32 cam ....sir what will be the components.....i am tight on budget ....i want to make a small drone having camera feature what will be components list plz write in comments

[@ArduJimmy]

nice. but I havent made drone with esp32 right now. many subscribers still building a drone with NRF24L01. I will make a drone with ESP32 later 🙏🙏🙏

[@robotronik2371]

Please we are waiting for test of this transmiter

[@ArduJimmy]

sure, together with video about altitude hold

[@ArduJimmy]

I think I will make a short video to test the transmitter. but my battery is bad and need to power together using USB power. wait

[@technonepal1681]

I love to wath your video .i appreciate your work .please could you make this type of drone using brussless moter.

[@ArduJimmy]

@technonepal1681 thanks so much. Actually, I really wants to make it using brushless, but my budget not supports right now. I'm working and struggle to save 🤭

Great Video,brother!🔥🔥 I tried making the transmitter and drone ,but im now stuck with the issue of nrf24 no communication, the transmitter and drone is connected but in multiwii config app, transmitter values are not changing in app. i know that the transmitter and drone is getting connected successfully as when i power the transmitter i can see the led in arduino of drone is getting brighter and when tranmitter is off the led doesnt light much. i also tested transmitter values in serial monitor (it works fine in serial monitor) and commented the print statements before final upload of code. i also crosschecked the nrf24 and arduino connection multiple times and it seems to be correctly wired. i also tried using different nrf24 module and same result. any idea what could be the problem, any ideas will be helpful.🙂🙂 Good luck with the project brother.👍 waiting for the testing video of transmitter.

[@ArduJimmy]

well, did you already check it using multitester? it must be 3.3v

[@CalvinSJ]

@@ArduJimmy ys i tested the voltage on every module including nrf24 and it seems to be giving correct voltage. I also tried the nrf checker code(transmitter and reciever code not single nrf24 checker code) from your github but no luck with that,it uploads fine but doesnt show anything on serial monitor it would be helpful if you post a video on testing nrf24 modules like, just a dummy code where one nrf24 module sends a text and the other module recieves and confirms the text send. I have also tried the single nrf24 checker code and it seems to provide correct information on serial monitor. Did you face any problem with communication with drone and transmitter during the project? Thank you for replying..🙂

[@ArduJimmy]

@CalvinSJ no. I provide the code so carefully and completely. You can add code to write on void setup() like this: Serial.begin(9600); and then uncomment all print line code void setup(){ Serial.begin(9600); //another vode below } when U write the Serial.begin(9600); you must take notice of uppercase or.lowercae letters since arduino ia sensitive case

[@robotronik2371]

Can i use this Mutliwii 2.3 for a up to 2kg drone?

[@ArduJimmy]

yes, but use brushless ESC and brushless motor for heavy duty. It will cost WOW note: you need to change GY-521 board type or based on your new spec yo make it work

[@robotronik2371]

@@ArduJimmy I want to use MPU6050, it will work right?

[@ArduJimmy]

@robotronik2371 yes you can, set minthrottle to 1000 and maxthrottle to 2000

[@AbdulGoni-c4w]

BG mau tanya kalo pake joystick stik bisa g

[@ArduJimmy]

bisa, asal bawahnya ada 6 pin. 3 pin sebelah dan sebelahnya jg 3 pin. kayaknya setiap joystick ntu pinnya 6 semua deh

[@AbdulGoni-c4w]

@ArduJimmy om boleh minta no wa nya g biar komunikasi enak

[@ArduJimmy]

@AbdulGoni-c4w cek di halaman about atau via facebook ntar tak kasih. tapi gak skrg diakusinya, besok aja. udh ngantuk wkkwkw

[@AbdulGoni-c4w]

@@ArduJimmy oke

[@raycraft3990]

If I throttle to 50% and then power off the transmitter, do all the motors stop after a few seconds? Does your nrf control drone has functionable failsafe feature ?

[@ArduJimmy]

nice question. Failsafe definition is disabled in my code, you can activate it by uncomment it. Since the min throttle is set to 1050 (ladybird) you can change it in #define failsafe: 1000 otherwise, it can not be armed

[@raycraft3990]

@ArduJimmy So, you're saying I should set #define MINTHROTTLE 1000 instead of 1050, and also uncomment #define FAILSAFE to enable the failsafe feature. If I don't change the MINTHROTTLE to 1000, even after enabling the #define FAILSAFE feature, then I won't be able to arm the drone. Did I understand you correctly?

[@ArduJimmy]

@raycraft3990 okay, let me repeat. this follows is failsafe config: #define FAILSAFE #define FAILSAFE_DELAY 10 #define FAILSAFE_OFF_DELAY 200 #define FAILSAFE_THROTTLE (MINTHROTTLE + 200) by enabling the failsafe, actually it works, if not, you must change to: define FAILSAFE_THROTTLE (1000 + 200) or define FAILSAFE_THROTTLE (1200) then, when you turn off the TX, the throttle will go to 1200 (unable to fly)

[@ArduJimmy]

Actually, mostly people Only wants to make a drone and fly. Just to make it fly. That's all. Only few people ask about BMP180 and BMP280 to make drone in altitude hold. No question or request about FAILSAFE config :p That's why I dont make a video about it. If most people can make it fly and want to know more about Multiwii Features, say, about 50% - of course, I will make a video about it

[@raycraft3990]

@@ArduJimmy If I want to stop the motors ,shall I set ( MINTHROTTLE +0) ?

[@nguyenloi2249]

hey admin can make drone + esc now? ESC tiny now?

[@ArduJimmy]

I already uploaded bro. check my videos

@@ArduJimmy hi, I want to create a pulse frequency of about 400 hz, how do I change the code?

[@ArduJimmy]

@nguyenloi2249 I think this is not a simple question and I must re-write the code for you. Guve me suggestion (at what media?) how to do this to make it simple because it is not proper to write here in this YT comment. are you referring to sending data at 400hz? or you want to control a pin output at 400hz? plese simplify your question (I would suggest to upgrade clock speed instead of fixing hz. e.g. by using stm32f series

[@nguyenloi2249]

@@ArduJimmy i say this esc

@nguyenloi2249 I still dont get it, bro. please simplify it into one concept of question or u can get in touch through my whatsapp (free)
