HC-05 Bluetooth module wiring

Here is the HC-05 Bluetooth wiring . This piece of wiring include a voltage divider to allow the 5V coming out of the arduino to be stepped down to about 3.3V for the HC-05 Receiver pin .

HC-05 Bluetooth module wiring

wiring main diagram

Here is the main wiring diagram . The wiring is divided small sectionS linked together using dupont connectors . This is for ease of assembly .

Hello my friend thank you for this good project , ı did this project with your party and software but ı got proglem here ,Please help me ı did this because of my school project .. 1- My tilt and recoil motors always working and dont stop this limits , ı try the codes change with chatgpt , it's find some problems and fix it , but its dont solve this problem ... I check servo motos it's working good. What you think about this problem ?

Finished mine today, I designed a very basic motor cover and electronics box with 3 leds for power, Arduino healthy and Bluetooth connected, thanks for the base!

Do you just download the app and it should work, I’m connected but the controls aren’t doing anything

Hi, can i use SG-90 servos instead of the MG-90s servos, does they fit into the 3d printed tripod and magazine?

I have a problem pairing the pc, the HC 05 bluetooth still flashes and cannot be paired. Can it just be a fault in the module or does it not have enough current for a small wire thickness?

Where is the detail. Can someone tell me where this dude gets a 1.5mm rod? Also, are these detentions length or diameter? (20mm rubber band?) This project is very cool and I am thinking about building something like this, but the parts list needs to be updated.

i think it is cause it is a .RAR file

HOW DO I GET A STABLE FILE

Little_french_kev

2 years ago

yes . A .rar file is an archive file, the parts are inside . Download winrar (it's free) then you will be able to get the STL file inside . Just a bit of advice : When you deal with a file with an unknown extension, google the extension (here .rar), more often than not you should find the answer to your problem pretty quickly .

So I used the wiring diagram to wire every up before assembly and it burned up my chip. Any idea what is going on there?

Hi can you help me with this? my servo motor keeps pushing the bullet non-stop and doesnt response to the 'shoot' button. is it because of the code or my servo motor? Thanks!

@g119 I could imagine, that all the current flows over your Arduino. An additional diode between Vin and the remaining consumers could help you. (or more your Arduino ;) ) But I also have a question for Little_french_kev: Have you measured the current of the 130 dc motors? Mine need about 2 A per motor in idle. I think that is a bit much...

Hi Little Kev, i'm sorry but can you give me a wiring diagram on UNO ? because I need to know how it's work on UNO

Little_french_kev

Hi , I haven't a diagram for the UNO but the wiring should not be different . the pins are just in a slightly different position on the board . If you refer to this picture you should be able to translate the wiring to the uno : https://cdn.instructables.com/F9J/QUME/INRCMG5L/F9JQUMEINRCMG5L.LARGE.jpg

Hi how could you do the shooting servo without any problem? Mine keeps shooting non-stop and cannot control via bluetooth

Hi there! can't wait to try this as a first project. would this work with an Arduino Uno as well? Also anything special needed for the 3d printer? special filament or something?

Little_french_kev

2 years ago

It should work with a Uno but it won't fit the bracket to attach it to the side of the turret . It should be pretty easy to work something out with some double tape or a few zip ties . Nothing special with my printer or filament . I just use classic PLA .

What are you trying to open it with ? The file you get when downloading from the website is an archive file containing the STL files, you need to extract them using winrar (it's a free software) .

Not sure if someone asked- hard to weed out from so many comments, but how would you automate this? Say, motion sensor activated or IR tracking to just blast people if they enter a "zone" and lock on to the target....lol
