Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about how can you make a simple program for DC Motor Speed Control using Arduino UNO. In my previous tutorial, DC Motor Direction Control using Arduino, I have just controlled the DC motor in both directions at constant speed using Arduino. I have also performed the DC Motor Direction Control in Matlab by sending different commands through serial port from Matlab and LabVIEW to the Arduino and then controlled the direction of rotation of DC motor. But in this tutorial I will rotate the same DC motor at variable speed in both clockwise and anti clockwise directions.
In my previous tutorial, we have seen that input pins In1 & In2 of mo ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity.
What is ESP-NOW Protocol?
Fig. 1: ESP-NOW Protocol
ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif.
Features of ESP-NOW Protocol:
It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using Wi-Fi.
ESP-NOW protocol does not require a handshake for establishing a connection but, they require pairing and once the devices are paired they can exchang ...
Hello everyone! I hope you all will be fine and having fun. Today, I am going to give you an elaboration on Introduction to UA741. UA 741 is basically a general purpose operational amplifier. This amplifier is considered to be ideal for the voltage follower applications because latch-up operations are no there in its case and it moreover it has High Common Mode Input Voltage Range (HCMIVR). UA-741 is a high performance operational amplifier made up of single silicon chip.
UA 741 is stable without using external components, due to the internal frequency compensation and this device is safe from the short circuiting. In order to cancel the effect of offset voltages we can use a small valued potentiometer/resistor. UA-741 can operate in a temperat ...

What are Flip Flops?
What are the types of Flip Flop?
How does we design the Truth Table of SR Flip Flops?
What are further classes of SR Flip Flips?
Implementation of SR Flip Flops in Proteus.
Flip Flops
Flip Flops are extremely important Circuits of Digital Logic Design. We Introduce the Flip Flops as:
"Flip Flops are type of sequential Logic Circuit that co ...
Hello Guys! I hope you are doing great and having fun. I am back to give you a daily dose of knowledge that will enhance your learning skills and put you ahead of others. Today, I am going to give you details on the Introduction to JFET. It is a Junction Field Effect Transistor that consists of three terminals named drain, source and gate. It comes in two configurations called the P-Type channel and the N-Type channel. I'll give you brief details on JFET and try to cover as many aspects as possible. Let's get started:
Introduction to JFET
JFET (Junction Field Effect Transistor) is a uni-polar voltage-controlled device that consists of three terminals called drain, source and gate.
Unlike bipolar junction transistors which are bipolar current-controlled devices in which a small amo ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share a new Infrared Sensor Library for Proteus. This IR sensor is not available in Proteus and we are sharing this library for the first time. I hope it will help in your Embedded Systems Projects particularly related to robotics and automation. So, if you want to work on this IR Sensor then I would suggest you to first design its simulation and then try your luck with hardware.
There are different types of Infrared Sensors & modules available in the market. Some of these modules have transmitter & receiver on separate chips and are mostly get activated when someone interrupts the light. The one we have designed has a transmitter & receiver on a single c ...
Hi Guys! Hope this finds you well. I welcome you on board. Thank you for clicking this read. In this post today, I’ll be explaining the Introduction to BC559.
BC559 is a bipolar junction transistor used to drive loads under 100mA. It falls under the family of PNP transistors and is mainly known as a current-controlled device. Where small current at one terminal is used to drive large current change at the remaining two terminals.
Read this post all the way through, as I’ll be touching pinout, working, datasheet, physical dimensions, power ratings, and applications of a BC559 transistor.
Let’s get started.
Introduction to BC559
BC559 is a PNP bipolar junction transistor mainly employed for amplification and switching applications.
It is com ...
Hello friends! I hope you are doing great. Today, we are discussing the latest version of the Arduino Mega 1280 library for Proteus. This can be used in both versions (Proteus 7 and Proteus. We have shared the previous versions, which are the Arduino Mega 1280 library for Proteus and the Arduino Mega 1280 library for Proteus V2.0 with you. With the advancement in the version, these microcontrollers have a better structure and the design is closer to the real microcontrollers.
In this article, I will discuss the introduction of the Arduino Mega 1280 in detail. Here, you will learn the features and functions of this microcontroller. Then, we’ll see how to download and install this library in Proteus. In the end, we’ll see a mini project using the Arduino Mega 1280 V3.0. Let’s move towards ...
Hello friends, I hope you all are having fun. In today's tutorial, I am going to share a new Proteus library for Raspberry Pi 2. We have already shared the Proteus Libraries of other Raspberry Pi modules i.e. Raspberry Pi 4, 3, Pico etc. and we discussed that these Pi modules won't be able to read the Python code. We have just designed the external appearance of these modules and you can use these Pi modules for circuit designing and project presentations.We have also added the Arduino firmware in these boards, which is just to provide a bit of interaction with these boards. We have given these boards an unofficial title "Arduino Pi".So, let's have a look at How to simulate Raspberry Pi in Proteus:
Raspberry Pi 2 Library for Proteus
First of all, we need to download the Proteus Library ...
