Can you make changes to the Demo 3 sketch and implement these scenarios (or whatever other improvement you can think of)?

When selecting a DC motor, you need to consider several characteristics that specify the electrical properties of the motor. This includes:

Our goal is to control the speed of a DC motor using an Arduino UNO and a potentiometer. A MOSFET is used because we can't drive a high-power inductive load with just the logic level output of the Arduino UNO. The MOSFET is placed between the Arduino UNO and the motor, effectively acting as a motor driver. The MOSFET is connected to the 9th pin of the Arduino UNO via a 1k Ohm resistor to limit the current.

The speed can be controlled by varying the number of turns in the field winding. This is achieved by tapping out the series field winding at several points, as shown in the figure below.

Thanks. The maximum current output depends on the transistor, in my case it’s TIP122 which can handle current up to 5A.

The motor supply voltage VM can be in the range from 4.5v up to 36v. You’ll also find the most important piece of information which is the pinout diagram and also a PCB layout example if you’re designing your own board, it’s going to be a good reference.

Connect one resistor to the power supply. One end of the wire must be connected to one end of the resistor. Using a middle-value resistor out of the set first will give you an idea of whether to increase or decrease the resistance depending on the speed of the motor.

A DC motor is a device that converts electrical energy into mechanical energy. Today, you find DC motors in many devices we rely on every day such as home and office appliances, automobiles, access control systems, and toys.

The basic idea behind PWM is that it switches the supply voltage ON and OFF very quickly. By adjusting the length of the ON/OFF pulses, we can set the voltage to anywhere between 0V and the maximum voltage. We will use this PWM signal to power the motor directly.

All direct-current motors must have two core elements: a stator and a rotor (armature), although critical functions can be performed by other components as well. A brushed DC motor comprises the following units:

Using any method of connecting the wires, securely attach the resistor to the power supply using one wire, attached on both ends, or by connecting the components directly together. The amount of resistors here may vary depending on what speed the motor must run at.

By decreasing the flux produced by the field winding, the speed can be increased and vice versa. Hence the name flux control method or field control method.

You basically right-click the project name in the IDE’s navigator and choose to create a new > source folder. And name it ECUAL and go to the GitHub repo, download the files and copy the “DC_MOTOR” folder and back to the IDE, right-click on the ECUAL and paste the library into it.

First to begin with, an electric motor is a machine that uses electricity to turn a shaft, thereby converting electrical energy into mechanical energy. Electric motors are broadly divided into the following three types.
