Hey Everyone,
Im a beginner and Im trying out a robotic car arduino project. Ive collected a few questions:

  1. Im using brushless dc motors, and they come with 3 cables with bullet connectors.
    How do I operate the motors the best way ?( using pwm ?)
    2)Why do people use arduino to operate an ESC to operate the motors versus just using the arduino to operate the motors?
  2. it seems that they run on a pretty high power. How do I know if its too much for the arduino ?
    Thanks in advance

How come that You face this project when it contains so many unknown parts?
Google each piece and learn more about them. There is a magnifying symbol up to the right. Search for Arduino + brushless motors.

  1. using an ESC
  2. because that's what they're designed for.
  3. because of the burning smell

Along with no brushes brushless motors don't have any way to switch current round to their different windings (which is what brushes/commutator do).

It's just about possible to do the commutation with an Arduino but it needs a lot of complex time-dependent code. That's while we generally use ESCs to do the work.

And the power for all motors, not just brushless, NEVER comes through the Arduino. You always use a separate power supply direct to the ESC or motor driver with just control from the Arduino.

The answer 3) is beautiful, classical and well known to most electrichians, the smell of "hot" or worse, burning…
