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

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.

We can order the PCB from JLCPCB which are the PCB fabrication service of EasyEDA, and also they are the sponsor of this video.

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.

I bent their leads on the other side so that they stay in position when I flip the board for soldering. As for the bigger components I used a masking tape to hold them in place when flipping the board.

There are different types of speed control of dc motor. Let us discuss, how the speed can be controlled with the above parameters.

When applied to the rotor, the electric current generates an electromagnetic field and makes the armature rotate. The similar poles of the field around the stator and rotor repel each other, which causes a unidirectional motion.

Controllers that do receive feedback from the motor are called closed-loop, or feedback, controllers. They can detect deviations from the desired values and correct the control signal accordingly.

Three or more wires are needed. Insulated wires work best as they prevent wires from crossing and the battery from short circuiting.

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

Time to do the wiring. You can remove the potentiometer to the circuit from Project 2 and replace it with the ultrasonic distance sensor. I am copying here the complete instructions so that you don't have to jump back and forth between the two articles.

we have plane to develop an Inveter using PWM principle, please assist me to develop it with your much needed ideas.

Before going further we need to discuss the H-BRIDGE. Now this circuit has mainly two functions, first is to drive a DC motor from low power control signals and the other is to change the direction of rotation of DC motor.

Compliance with the system requirements is the basic principle you should follow while selecting components for your DC motor controller schematic. This relates to an MCU, gate drivers necessary to control the transistors, and other components.
