Controllers are classified into digital and analog versions. The main difference between a digital DC motor controller and its analog variant is that the former comprises microcontroller (MCU) based hardware and firmware. 

Upload the sketch and play with it to get a sense of it in “real life”. Try to imagine how it would behave in a real situation. Can you foresee any limitations? Can you imagine any improvements?

So in this article, we will cover the basic concept of controlling the speed of a DC motor with a potentiometer, using Arduino’s PWM signal with the help of a MOSFET Transistor. Below, you can see a working setup of our project, which we will be building in this article.

Figure 3: The changing resultant flux continually pulls the rotor magnet, causing the rotor to turn.

The other classifications are typical of almost any electrical motor’s controller. Let’s briefly go over them through the example of a brushed DC motor controller.

Primarily, there are two types of loads: resistive and inductive. When selecting components based on the type of load, it's important to remember that if you are working with an inductive load, such as a motor, you should add a diode in parallel with the load to protect the FET from generated reverse EMF.

Test the circuit. The DC motor should now be spinning if all components are securely connected. The resistance provided by the resistor(s) determines the speed the motor will run. If the motor is not running, check all the connections to make sure the circuit is securely connected. If the motor still doesn't run, check that the battery is not dead by connecting it directly to the motor and replace or recharge if dead.

A linear regulator keeps the output voltage at a constant level with a resistive load. The output is stable pelo matter what input voltage is supplied by the power source.

We’ll have to do this step just to have the TIM_HAL files added to our project by CubeMX. And also it gives us a startup configuration for the PWM channel of that specific timer module as we’ll see hereafter. This is the best way to keep the code generic and portable to any STM32 microcontroller.

Circuit diagram of DC motor speed control using arduino is shown in the figure below. The working principle and program of this circuit is same as that of the LED brightness control. Only difference is that and additional motor driver circuit using a transistor is included in the circuit.

For example, in the current version of the sketch, the vehicle would come to a complete stop only when the distance to a wall was 0cm.

We can use the Silk layer to add text to the board. Also we are able to insert an image file, so I add an image on of my website logo to be printed on the board. At the end using the copper area tool we need create the ground area of the PCB.

Finally, the control resistance is removed completely. Now each motor has half of the line voltage across it. So the motor will run half of its normal speed.
