Im currently building this project and thank you for your thorough documentation. Im only having 1 issue, which resistor goes were. I cant make out the labelling on the wiring diagram. I think it says the 10kΩ between the mosfet and the nano, but the other 2 im not sure. Any help would be awesome.
I put a 680 ohm resistor between the ground and the HC-05 RX pin . And a 330 ohm on the HC-05 RX wire . The idea is to create a voltage divider to lower the voltage going to the HC-05 Rx pin (it is supposed to work on 3.3v and the arduino is sending 5v) . You can read more info here : electronics.stackexchange.com/questions/280500/why-do-you-have-to-use-a-voltage-divider-with-hc-05-bluetooth-module-arduino/280532 Hope this help .
For the servo that holds up the upper part of the turrent you will need to get a larger servo because that weight will brake the servo motor contraption
Perfeito! Parabéns incrível. Estou procurando os componentes para iniciar uma. Por favor me tire uma dúvida. Quantos RPM e Volts o motor que você usou? A torre pode ser alimentada por um bateria de 9V ou 12v
you said to use a power supply of at least 9V 2.5A on your website. Is 9V 5A enough power? Sorry for the stupid question. I am very new to electronics and want to be safe. The turret is awesome by the way!
Thanks! The 2.5A figure was calculated for using 3 MG90s . If Google is right an MG90s draws around 120-250 mA and up to 750mA if stalled ( this shouldn't happen if the turret is setup properly ) . Each motors can draw up to 800 mA . The arduino shouldn't draw much current, let say 50mA . The total current needed should be : 3*250 + 2*800+50 = 2400mA ->2.4A (just under 2.5A) MG996r are power hungry you will need more than 2.5A . From the tower pro datasheet below you can see each of those servo normally draws between 500mA and 900mA and up to 2500mA if stalled . www.electronicoscaldas.com/datasheet/MG996R_Tower-Pro.pdf following the same logic with 2 MG996r you end up drawing : 2*900 + 250 + 2*800 + 50 = 3700mA -> 3.7A These are pretty rough estimates but with a 5A power supply you should be fine .
When will you upload the making video of the updated turret (brush less motors and *camera*) ?pls tell me if it will be late i will continue with the bluetooth nerf turret otherwise I'll wait and i will do this one.because i have to do college project in September.and can you say the main advantage of this turret in the society.pls reply fastly bro so i would be thankful to you so much.
hello my friend ı make this project but 2 motor always working and ı have no idea what about that ?I try with Uno and Nano but resault doesnt change ? maybe u can help me? 2 servo always working and ı cant control them .
Hello, today I went to test the nerf turret for the first time and the program was crashing after attempting to connect to Bluetooth. I think it may have something to do with a new version of Arduino 'nano every'. Do you have any input on this or know where the code may have something outdated? Thanks!
I tried running them on 6V, at that voltage the dart would barely have any speed . Although the motors I bought were rated for 9V I suspect they might not be different from the 6V ones . I bought the motors from here : thepihut.com/products/dc-toy-hobby-motor-130-size?variant=27740465105¤cy=GBP&gclid=CjwKCAjwyvaJBhBpEiwA8d38vJH47sIoF6N7ZeXY8juEvg71-3e7ol5MEJAYyh9bty0lr6-2L3BPxRoC8BgQAvD_BwE
I your motor is rated for 9V it's probably not last as long if you feed it with 12V . I ran mine on higher voltage and I didn't experience any major issue .
Hello, I really appreciate all the work you've done here and ive had alot of fun building this project. My only problem now is that I have been unable to download the windows app to run the turret. Whether on your site, or github, when downloading executable it simply tries to reinstall arduino. Any help would be great! Thanks again.
I am not familiar with the SG90's servos but from quickly looking at datasheets they seem to be the same size of the the MG-90's so they should at least physically fit . I would assume they would work but could probably fail quicker under quick change of direction as they have plastic gearing .
I think you gotta control it via code. Id imagine if you make a loop for it to just to make the things spin and push it would be fine. And make run indefinitely.
Spy sappin my sentry
I get this reference.
Target acquired.
... Are you still there?
... Goodnight.
You think about a version with Camera Face detection?
Use BB bullet to make trust bearing on first axis then all perfect!
yes . The base definitely needs some love!
@@Littlefrenchrobot You inspired me now I planned ta make one!!
one 3d part is missing shaped an plus 2:02
Step 1: own a 3D printer
Me: Welp. Saved to watch later for when i get one in 15+ years
step 1 : find a rich friend
step 2 : borrow his 3D printer
step 3 : build it!
Step 1: Find a 3D Printing service
Just email us and get the printed copy delivered at the student price! We are a student supporting 3D printing provider too
Isn't there 3d printers at like Barnes and nobles
Fantastic video. Are you going to offer the STL files?
Thanks! Yes, I will make them available alongside with the code/apps(android and PC) when the project is complete .
@@Littlefrenchrobot Fantastic. I found your video in the arduino facebook group. Keep up the good work.
Amazing, I come from the arduino forum and I let my like.

Could this be done with 6V 130 dc motors? I can't seem to get my hands on a motor with the same size and more than 6v. Where would you buy your parts?

Can I use SG90 micro-servo in this project? Any help would be greatly appreciated!

@@Littlefrenchrobot Ok, thanks for the help! It’s a really cool build!
@@Littlefrenchrobot Just one more question. Does the other versions of the arduino work in this build? Like the arduino uno?
@@Arvid-ls7nu I haven't used Arduino board in a while but if I remember correctly the pinout are very similar on Nano and Uno so it should work .
@@Littlefrenchrobot Ok, thanks alot!
Does it work by itself or we have to control it
I think you gotta control it via code. Id imagine if you make a loop for it to just to make the things spin and push it would be fine. And make run indefinitely.
Late question
where should i purchase the parts,screws, and wiring
Alibaba or amazon
please tell me the name of all the screws you have used
they are M2x10mm self taping screws
This parts are mm or cm ?
I design them in mm . You should notice pretty quickly if the scale is wrong is your slicing software !
Can we use sg90 servos in this project?
I have the same question! Any help would be greatly appreciated.
Are the files on Thingiverse?
no . but they are on my website .
Please 3 do printed link
It's COOL!
thanks!
Nerf would charge 200 dollars for this
This amazing for rat hunter
What language does this use
Python for the PC side and C/C++ for the arduibo .
@@Littlefrenchrobot ok
@@Littlefrenchrobot ok so C++ does work
Cuz i dont know c
Very terrible project and worth the application .. Thank you for this creativity
?! it’s awesome
Meant to say terrific
poor design. the bottom is too light and u dont even know where ur aiming. at least strap a laser next to the barrel.
