hi
i have stepper motor nema 17 with feedback smart circuit with buit in arduino ic and 4
pins output is scl and sda and 12v power with ground pin i want to know about the pin diagram and programming
pins output is scl and sda and 12v power with ground pin i want to know about the pin diagram and programming
If you can, post a link to specification of the device "feedback smart circuit".
Thanks
Where do you see any Arduino there?
i do not have any specification and do not mention the model no on this circuit
arduino atmel 328 mega ic is sold in this circuit board
Arduino uses an ATmega386 MCU on some boards. But this is not a special Arduino MCU. This MCU is used in thousands of commercial applications worldwide that have absolutely nothing to do with Arduino.
Without a detailed technical specification of exactly this device ... no chance.
i will send you the proper pictures of this circuit board i did try to findout the detail but it is not available here
It is not unusual for manufacturers not to publish their technical data. Most don't.
this is all picture using arduinio mega and steppers motors from the begining i want to move steppers in degree basic program
The circuit board I am using is v1.0 stepper motor controller.
Hi, @halari
Welcome to the forum.
Please read.

Can you please post a link to where you purchased the stepper?
Thanks.. Tom... 
i have not purchased i am new in lab before i join the lab 1 person is doing work on this project

this information i have available so i thought in my mind controller and motor driver in 1 circuit also encoder has attached in this circuit i need to burn the code from another arduino mega and control this motor if you have guide me the code and library of arduino which code and library will do work
Well find out where, it is important as you show two PCBs in your images, and yet only have schematic for one.
The PCB on the Mega is also important too.
Who connected the project up as it is now?
Do you have a schematic?
If not, then reverse engineer your project and draw one.
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
Can you please tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom...
How do you know it's an Arduino? Is there a bootloader? Do you know how to burn a new program to it?
i have findout the schematic of circuit diagram

I am electronic engineer have an little bit experience of programming and electronics phisically
first i have to start basic code uploading in this controller can you guide me that i need to connect the resistor in between reset pin?
yes i have done before when i did make a new arduino controller burn bootloader as well upload the code but rightnow i have confused somethings
