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 t ...
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 pro ...

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 sh ...
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 correspon ...
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 L ...
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 f ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to explain the Relay Interfacing with Microcontroller using ULN2003A. In the previous lecture, we have discussed the detailed Introduction to Relay along with its working. Now we are going to practically interface the relay with a microcontroller to design an automatic switch. Relay is a key component in almost every electronic circuit. It can be
used as a switch and can also be used as a voltage regulator.The microcontroller I am going to use here is PIC18F4552 but you can use any other Microcontroller. You just need to change the syntax of coding but the logic will remain the same. Here, I am using ULN2003A to control the relay and from this relay, we can control anything.So, let's get started:
Relay Inte ...
Hello everyone! I hope you will be fine and having fun. Today, I am going to give a detailed Introduction to Relay. In this tutorial, we will learn the basics of relays, the working principle of relays, the types of relays and their applications in detail. A relay is a simple automatic switch that opens and closes the circuit(either electronically or mechanically) based on its input signal. A relay is an electromechanical switch that uses electromagnetism from a small current or voltage to switch higher current or voltage for different appliances. When a relay is in a Normally Open (NO) state, no current passes through it and when the relay is energized, the current starts to flow and we can say the relay is in a Normally Closed state. You should also have a look at Relay Interfacing with ...
