Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation . If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons. First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.). Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly). Because of these two reasons, we have to use the driver in between the microcont ...
Update : We have created a new version of this library, which you can check here: Arduino Pro Mini Library for Proteus V2.0 . Hello friends, hope you all are fine and having fun with your lives. In today's post, I am gonna share Arduino Pro Mini Library for Proteus. Recently, I have shared Arduino Nano Library for Proteus , and before that I have also posted Arduino UNO Library for Proteus as well as Arduino Mega 2560 Library for Proteus , and now I am gonna share Arduino Pro Mini Library for Proteus. Arduino Pro Mini is another Arduino board which also uses the same Atmega328 Microcontroller and has almost the same number of pins as Arduino UNO and Arduino Nano. Arduino Pro Mini is even more smaller than Arduino Nano board. It doesn't have the programmer on it so if you need to program it ...
Update : We have created a new version of this library, which you can check here: Arduino Mega 2560 Library for Proteus V2.0 . Hello friends, hope you all are fine. In today's post, I am going to share Arduino Mega 2560 Library for Proteus. In the previous post, I have shared the Arduino UNO Library for Proteus and I have mentioned that I am gonna share more Arduino Libraries soon. Actually these days I am quite excited about this Proteus component designing and I am designing the Arduino boards as a starter. So, till now I have designed two Arduino boards in Proteus. First one was Arduino UNO which I have provided for download in previous post and today, I am going to share Arduino Mega 2560 Library for Proteus . In the coming posts, I am gonna share more exciting libraries for Proteus as ...
Hello friends, hope you all are fine and having fun. In today's post we are gonna have a look at LM317 Voltage Regulator in Proteus. In the previous post, we have seen how to design a 5V Power Supply in Proteus ISIS , which I have designed using IC regulator 7805. Today I am going to share How to design LM317 Voltage Regulator Circuit in Proteus. This DC power supply is a variable one means you can set its output voltage to any level you want. In order to change its output value we have used a variable resistor and by changing its value you can change the output value. It is a basic level project and very simple but used as a base to design large industrial projects. In this project, we are going to control the speed of a DC Motor and the corresponding voltages, appearing across it. The re ...
Yesterday, I have posted a new Arduino Lilypad / Nano Library for Proteus in which we have seen how to add that library into Proteus so that you could be able to use these boards in Proteus. That was quite easy. Today I am gonna post a small project in which we will see how to use that library and produce an Arduino Lilypad simulation in Proteus. In this Arduino Lilypad simulation in Proteus, I am gonna use obviously he Arduino Lilypad board along with few LED lightsand will make them blink. Its also quite easy and you can also download the simulation and the hex file at the end of this project but I would suggest you to do it yourself so that you learn something out of it. Before starting this project, you must have first integrated the Arduino Lilypad Library as without it you wont be ab ...
Hello friends, few day ago I have posted a tutorial on how to do Arduino Simulation in Proteus . In that post, we have used an Arduino Library for Proteus but as this library is in its initial phases that's why currently it supports only three basic Arduino boards which are Arduino UNO, Arduino Mega2560 and Arduino Mega1280. But as we know there are numerous Arduino boards which are used these days. So, I searched a little and I came across this amazing Arduino Lilypad Library for Proteus which has the support for few other arduino boards, so I thought to share it with you guys. I have tested this library myself as always and its 100% working. I have tested it on Proteus 7 and I think it will work fine on Proteus 8 as well. As we have the support for above three boards in the previous libr ...
Hello friends, I hope you are doing well. In this tutorial, we will compare alternating current and direct current, calculate power in both systems and explain why modern electrical networks use each form. AC and DC describe the direction and time variation of voltage and current. Power is the rate at which electrical energy is transferred. The phrase “AC power” therefore means power carried by alternating voltage and current, while “DC power” means power carried by quantities with fixed polarity. Figure: A conceptual image introduces the comparison of alternating and direct current. AC and DC at a Glance Feature DC AC Polarity Remains fixed Reverses periodically Typical waveform Constant or varying unidirectionally Sinusoidal or another bipolar waveform Frequency Zero for ideal steady DC ...
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.
