Hello guys,
I'm working for a school project and I 3d printed a excavator.
So, my question is if i can connect 3x 12V DC Motor ( FIT0489-D - the model of the motor ) for the 360 rotation and 2 for going forward and backward.And then I want to connect 4 push rods for the arm of the excavator.
And then after all this i want to install a bluetooth module to control the excavator by the phone.
Thank you!
Yes, but a better title for the question would be "Excavotor controlled by Arduino".
The Arduino is not a power supply. But motor control circuits can be attached, so the Arduino can make them go or not, backwards or forwards, slow or fast.
arduino control dc motor
and settle in.

The motors must all be powered separately from the Arduino. Don't forget to connect the grounds!
Never use an Arduino board to power things like motors, solenoids etc. Powering a few LED is okey.
Your picture shows what is called a "linear actuator". You will need an "H" bridge module to control the polarity to the actuator so it can go out and back in. And one "H" bridge for each linear actuator. Are you going to use the linear actuators in pairs?
Ok. Thanks for the picture.
Expect to spend LOTS of time making the pair share equally in the forces to push and pull.
how many h brigdes do i need for the actuators? And how many for the dc?
Add h-bridge to the search I suggested.
Avoid using the L298N, a popular 20th century part which still pops up all the time. Shop at pololu.com, or at least start there, to see the variety of choices.

what do you think about l293d?
Well, one per linear actuator. Except where you plan to use two together. Then you need one h-bridge with current handling capacity for then two actuators acting together.
Worse than the L298. Pololu has a great collection of modern, efficient motor drivers. Buy one that can easily handle the stall current of the actuator you choose.
