Hey everyone ,
I am completely new to this forum as well as to everything that has to do with coding , motors , etc ...
What i've been trying to figure out (not having knowledge nor experience about everything that has to do with mechanics) , is how to make my setup work . My goal is to create a type of follow focus mechanism for a big photography lens i have .
Here is an example of what i am trying to create , found this guy who had the same idea and already did it (i have the same lens) : [DIY] Motor Focuser for Telephoto Lens-MotorTest - YouTube
The pieces i bought are :
Arduino Uno
DRV8825
Breadboard
Wires
Rotary encoder
Nema 8 stepper motor
Rechargeable 12V battery
I attached a couple pictures so you can see my setup till now . I actually followed the instructions on one of the pictures attached .
Something weird happening (i don't know if it's normal) , whenever i connect the negative of my battery to the GRD and the positive to the VMOT of the drv8825 , while the arduino uno is connected to my pc , i get a weird noise coming from my macbook pro .
Anyways , i would really appreciate everyone's help . This could really be complicated for someone not having any past experiences with the subject , and i feel that my brain is about to explode trying to figure out something i'm totally not familiar with .
So if anyone is able to help with the setup (as a start) , i would be more than grateful . Then the only thing left to do is coding , but we'll get to that later on .
Cheers
