Hello friends! In the previous tutorial, we controlled the direction of a DC motor in Proteus . Now we will work with a stepper motor, where rotation depends on applying an ordered sequence to the windings. We will begin with the original six-wire simulation, inspect the sequence manually, and then explain how a microcontroller and driver can generate it. The original screenshots use Logic State sources to make individual winding states visible. They are useful for understanding the sequence, but they are not a physical driver circuit. We will preserve the images and add the missing distinction between simulated logic sources, microcontroller outputs, and the winding-current path. By the end, you should understand unipolar and bipolar wiring, wave drive and half stepping, direction reversa ...
Hello friends! In this tutorial, we will design a DC motor control demonstration in Proteus ISIS and then connect its control logic to a PIC16F877A. We will begin by observing how voltage polarity changes the direction of a simulated motor, then explain the driver stage needed between a microcontroller and a physical motor. The original article used Logic State sources and a simplified direct connection to illustrate direction changes. We will preserve those screenshots, but label their purpose clearly. Logic sources and PIC output pins are not substitutes for a motor power driver. The updated practical interface uses an L293D bridge example, with separate logic and motor supplies. We will also correct the relationship between the original schematic and code, add explicit stopping behavior ...
Hello friends! In this tutorial, we will explore the components and instruments available in Proteus ISIS and learn how to choose the right item for a circuit. Finding a familiar part name is only the beginning. We also need to know whether it has a simulation model, which properties must be configured, and whether the item belongs to the schematic, the measurement setup, or a later PCB design. This article continues our practical Proteus series after designing an LCD circuit with a PIC microcontroller . We will cover ordinary components, displays, motors, serial tools, and shift registers, then connect each topic to the more detailed tutorials already available in the series. My aim is to help you build a sensible test circuit instead of placing unfamiliar parts and hoping that the simula ...
Hello friends! In this guide, we will learn how to use Proteus ISIS and ARES, starting with a simple circuit and gradually moving toward microcontroller simulations and PCB design. I have kept the original tutorial collection so that you can follow a lesson in detail whenever you reach that stage. Our goal is to understand the complete development process. We will draw a circuit, calculate what it should do, simulate its behavior, examine signals with instruments and then prepare a physical board layout. Each stage answers a different question, so a successful simulation is one step in the process rather than the final proof of a finished product. If you are new to Proteus, follow the sections in order. If you already use it, choose the topic you need from the linked lessons. Some screensh ...
Hello everyone, I hope you are doing well. In this tutorial, we will compare DC and AC motors from their operating principles to their speed control, maintenance and applications. Both convert electrical energy into mechanical energy through electromagnetic force, but those broad labels contain several different motor families. The first important correction is that an AC motor is not simply a DC motor with continuous slip rings. Most industrial AC motors create a rotating stator field and use either induction or synchronous interaction to produce rotor torque. We will therefore compare common brushed DC motors, brushless DC motors, induction motors and synchronous AC motors. Figure: A small DC motor introduces the comparison of DC and AC motor operation. DC and AC Motor Comparison Feature ...
Hello friends, I hope you are doing well. Welcome to our Difference Between engineering series. In this series, we compare two related technologies side by side so you can understand where they are similar, where they differ and when each one should be selected. A useful comparison goes beyond short definitions. We will begin with the physical principle, compare construction and operating behavior, add equations or ratings where they clarify the subject, and finish with practical selection guidance. This format is useful for students preparing for examinations and interviews, but it is equally useful when an engineer must choose between two real design options. Figure: Banner for the engineering comparison series and its tutorial index. Difference Between Tutorial Index No. Comparison Main ...
Hello everyone! I hope you are doing well. In this tutorial, we will study the relay from its basic construction to practical selection and control. A relay allows one electrical circuit to operate contacts in another circuit. This makes it useful when a low-power controller must switch a different voltage, a larger load or an electrically isolated circuit.
