With the help of our 2-channel BDC motor controllers, users can control robots remotely via a wireless communication module. Our team provided electronic design and embedded software development for the project.

That’s why the DIR1 & DIR2 pins are not useful in this LAB, despite the fact that they’re already initialized and reserved by the DC Motor library for DC_MOTOR1 structure.

I believe that the combination of brilliant minds, bold ideas, and a complete disregard for what is possible, can and will change the world! I will be there when it happens, will you?

In addition to closed-loop control, advanced DC servo motors with a variable speed DC motor controller show high performance and reliability in complex industrial applications.

Let's try a variation of the Project 2 experiment: control the speed of the DC motor with an ultrasonic distance sensor. Of course, we'll use an Arduino and the L298N motor driver.

Also the transistor acts as a switch. When the output from the Arduino pin 10 is LOW then there is no base current, the transistor is driven into cutoff region of operation and therefore there is pelo collector current. In this case there is no current flowing through the DC motor.

In this article, I will describe one last experiment that involves a DC motor. We will connect an ultrasonic distance sensor in the place of the potentiometer, and use that to control the rotational speed of the motors.

If this causes many problems, a switch may be installed between these components to shut off the circuit when needed. Once both ends of the wire are connected, the circuit will be ready.

Typical configuration: three coils with 120º spacing. Driven by controlling the phases and coil currents.

To change the direction of rotation the PWM of timer is connected to the second signal pin.                                                      

Here’s a basic circuit of the 555 Timer operating in an astable mode and we can notice that the output is HIGH when the capacitor C1 is charging through the resistors R1 and R2.

In both circuits shown above the arduino is supposed to be powered through the 9V external power input jack.

A stepper motor belongs to the group of brushless DC motors, but its distinguishing feature is that it rotates in stages or steps. After each step, the rotor stops at a certain angle.
