How to control a BLDC with an Arduino

This tutorial guides you through setting up an Arduino with a potentiometer to control a brushless motor. It covers the necessary components, wiring connections, and programming the Arduino to read potentiometer values and send pulse width modulation signals to a speed controller. The tutorial concludes with testing the setup to control motor speed using the potentiometer.

What is the purpose of connecting the white signal wire of the speed controller to port nine of the Arduino?

• To power the Arduino

• To send a pulse width modulation signal

• To connect the motor directly

• To ground the circuit

Which component is connected to the positive rail and the negative rail of the breadboard?

• Arduino

• Speed controller

• Brushless motor

• Potentiometer

What library is used in the Arduino code to control the motor?

• PWM library

• Motor library

• Servo library

• Wire library

How does the Arduino convert the voltage reading from the potentiometer?

• Into a frequency

• Into a digital signal

• Into a number between 0 and 1023

• Into a binary code

What happens when the potentiometer is at its maximum position without the final part of the code?

• The motor reverses

• The motor stops

• The motor speeds up

• The motor stalls
