Hi,
I'm a very beginner , but I would like to learn to do something in arduino.
I have a nano v3 board and some modul ( vl53l0x, neo8N GPS, MPU9250, AHT10, 4 ea SG90 servo, A2212/6T motor)
First of all. Do I need any part for it to connect together all of them? And how can I put on the board if almost everything use the same pins (aka: VCC,GND,SCL,SDA). After when I can connect all of them correctly and get datas on the serial monitor after that I can try to learn ,how I can modifie the behavier of each other to reach the goal .
Don't ever think about connecting "all" and the start coding. It will never work.
Connect one sensor, or one motor, relay.. and make it work. By then You've learned how to handle that unit.
Then You can approach the next device.
I mean, the end of the goal would be to connect all of them, so I just want to know what else I need to buy for it.
And I would like to start to design the device shape and which module where need to put .
Of course I will test every modul one by one first, but after that I need to connect all of them to do such a code to take the data from one of the modul and provided to another one.
one kind of sensore fusion
And how can I put on the board if almost everything use the same pins (aka: VCC,GND,SCL,SDA).
SCL and SDA can connect to multiple I2C devices, just parallel the wires. Devices can co-exist on the same wires because each one has a different digital address.
But I only see two of your devices that actually use I2C.
The Arduino can't power any servos or motors, so plan on powering them separately. Don't forget to connect all the grounds.
Wires... power supplies... perfboard may be useful to solder everything onto...
Get building and buy stuff as you need it! I've never managed to buy everything I need beforehand. Plans always change along the way, leaving you with unused parts in the end and still buying stuff along the way.
leaving you with unused parts
.... which are still not the right parts for the next project.
some bright guy found a solution for your multi wiring problem:
with luck they will eventually make shields for al the major boards
I use mini breadboards:
and double row headers and a soldering iron and make my own proliferators for +5V, GND, SCL & SDA
I have a same shield board and there will come a bredboard tomorrow. But I don't know these boards have pull up resistor or not or I need to put in the circle anyway. Anyone has info that there is any chance to use the brushless motor (T-Plug ESC) without LI-PO battery connected into the 220V via USB like a mobile charger?

What is the voltage and current rating of the motor?

Hi,
I'm a very beginner ,
Fix that bit first.

+!
Fix the hole byte, then word and long words would come within reach.
aarg:

the motor is A2212/6T 2200KV and 30A ESC for it.
The ESC is DC:5,5-12,6V BEC 5V/2A
Hi, I started to familiar the moduls, but none of them want to work like in the YT videos.
I tried the neo M8N GPS modul.
Most of the time when I see they use the GND,5V, RX,TX pins. and it is work.
But somebody sad to me, to need to use it GPS RX->arduinoTX, and GPS TX-> Arduino RX.
Or there are some diffenrentia between UNO and the NANO. because most of the user use the UNO and not the NANO.
I tried to upload an empty scratch to see the data, but mine is not just sending readable data like the others.
And They use usually the 9600 boud for me just the 115200 boud give these data.
How can I set up the default value? Or it doesn't matter that the module send these data too?
How can I set up the default value?
Download and read the sensor data sheet. That is always a first step.
Make sure that you get each tiny piece of the project working, and understand how it works, before moving on to the next, or adding any parts together.

Negligible differences. The Nano is a better form factor for a project unless you insist on using a "shield" that fits on the UNO. People use the UNO mainly as that is unduly heavily promoted as a "beginner" device.
