How many sensors, drives, can be connected to arduino?

Question

Arduino

Hello! I wanted to make a project in which I would have to connect to the Arduino uno:
x2 stepper motors with drivers, x4 servos, and an hc-rs04 sound sensor (there is a breadboard).

They will all need to be connected to the Arduino uno. And I'm interested in the question:
Will there be enough power ports and pins?

For example, I could connect 2 stepper motors to ports 4,5,6,7, 8,9,10,11 to both 5v and 3v.
And the sound sensor to ports 12,13 and to vin. But what about servos?

Or do you need to buy a powershield? Or switch to another micro?

Answer 1

You will feed them separately. Enough control contacts

Answer 2

Stepper motor drivers need only 3 connections - step, direction, enable. However. the enable line can be neglected if there is no need to disable the motor shaft hold. It is desirable to connect servos to those arduino outputs that are covered by the hardware PWM generator. Ultrasonic rangefinder - no matter where. Should be enough for everything.
