Hope this article has helped you to better understand how to incorporate DC motors into your electronics projects! Leave a comment below if you have any questions.

A traditional BDC motor controller circuit is an H-bridge. This is an electronic circuit with four open/close switches that supply positive and negative voltage by turns.

Note that: I’ve deleted the Automóvel-generated TIM2 initialization function and its parameter. Since our DC Motor library will handle that, we don’t need that function at all.

Generated because of the constant switching of the commutator, it affects neighboring electronic components. To reduce it, you could implement different filters that protect the wires from EMI.

The field coils can be paralleled with additional winding to obtain the required speed. It can also be done by regrouping the field coils in the motor, as shown below.

The example LABs will put everything under test and you’ll see how and when to use each of these functions.

will increase and subsequently motor speed will decrease. Thus the speed can be controlled by varying the resistance in the diverter.

Note that: I’ve deleted the auto-generated TIM2 initialization function and its parameter. Since our DC Motor library will handle that, we don’t need that function at all.

As I’ve stated earlier in this tutorial, my DC Motor driver (library) gives the user full control over the PWM signal’s resolution.

Once we are done with the design we just need to click the “Gerber output” button, save the project and we will be able to download the Gerber files which are used to manufacturing the PCB.

As the wiper moves from one side to the other, it generates a different voltage within the range of 0 to 5V, which is fed to the 10-bit ADC of the Arduino UNO.

PWM is a method through which we can generate variable voltage by turning on and off the power that’s going to the electronic device at a fast rate.

There are several ways to generate the PWM signal for the motor, but in this tutorial we will use the 555 timer. Here’s a schematic of the circuit:
