Test the circuit. The DC motor should now be spinning if all components are securely connected. Rotating or adjusting the potentiometer should change the speed of the motor with either limit being the motors fastest speed, and the slowest speed the potentiometer can provide. 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.
When selecting a DC motor, you need to consider several characteristics that specify the electrical properties of the motor. This includes:
Most FETs on the market have a built-in diode that performs this function, so in that case, an external diode provides Em excesso protection. For resistive loads, such as LEDs or heaters, there is pelo need for additional protection since they have a straightforward linear relationship between voltage and current.
AC motors are driven by alternating current, and stepper motors are driven by pulses of electric power. DC motors on the other hand are powered by direct current, and have the following features.
You can always show your support by sharing my articles and tutorials on social networks. It’s the easiest way to support my work that costs nothing and would definitely be appreciated!
For example, if you touch the base with your finger it could cause current into the base and the motor will rotate. This is not mandatory but it is good to include to reduce chances of accidental starting of the DC motor. The DC motor is connected as load at the collector.
If the button is pressed if the figure, then the motor will start rotating and it will be in motion until the button is pressed. This pressing is continuous and is represented in the first wave of figure. If, for a case, consider button is pressed for 8ms and opened for 2ms over a cycle of 10ms, during this case the motor will not experience the complete 9V battery voltage as the button is pressed only for 8ms, so the RMS terminal voltage across the motor will be around 7V.

Connect the other terminal of the DC motor to the unused terminal of the power supply. If the power supply is not off or has no switch, then the motor may begin spinning once it is connected to the power supply.
As I’ve stated earlier in this tutorial, my DC Motor driver (library) gives the user full control over the PWM signal’s resolution.
After some Net searches, I found various datasheets from different manufacturers, leading to some confusion due to the different models available. If you have a motor from an authenticated manufacturer, refer to their datasheet for accurate specifications.
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.
However, in case the PWM frequency is too high, the MCU may have problems with generating PWM signals of the required value. In addition, the very high frequency may lead to the malfunction of the gate driver and transistor switches as they may not be compatible with it.
After inserting the components we need to create the board outline and start arranging the components. The two capacitors should be placed as near as possible to the 555 Timer, while the other components can be placed wherever we want, but still in a logical arrangement according to the circuit schematic.
