Hello friends, I hope you all are going great. Today, I am going to share the 10th tutorial of Section-III in our Raspberry Pi Programming Course. In our previous tutorial, we interfaced a Gas Sensor MQ-2 with Raspberry Pi 4. Today, we will be interfacing a Fingerprint Sensor with Raspberry Pi today.
After appearing only in science fiction films until recently, fingerprint sensors are often employed to confirm an individual's identity in various contexts. Today, fingerprint-based systems are used for everything from checking in at the office to verifying an employee's identity at the bank, withdrawing cash from an ATM, and proving one's identity at a government agency. For identifying purposes, fingerprint-detecting technology has been used for so ...
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 ...
Hello friends, I hope you all are doing well. In today's tutorial, I am going to share a new Proteus Library of ESP32 embedded module. ESP32 is a microcontroller board used mostly in IoT projects. It's a successor of ESP8266 or NodeMCU. We have already shared the NodeMCU Library for Proteus and I hope you guys have enjoyed it.Proteus software is not capable of handling WiFi or BLE technology, thus we can't implement these technologies in the ESP32 board. Though, you can use its input/output pins to interface embedded sensors and modules. You can also use it to design the Circuit Diagram of your Project.So, let's have a look at How to simulate ESP32 board in Proteus:
ESP32 Library for Proteus
First of all, download the zip file of Proteus Library for ESP32 board, by clicking the below b ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to LM2575. LM2575 is specially designed to simply the design of switching power supplies. It can be done by providing all the necessary active functions required in Integrated Circuit (IC) for step down regulators. LM-2575 can deliver load current of around 1A along with the good line regulation as well as load regulation. LM 2575 has different builtin functions e.g. frequency compensation, cycle by cycle current limiting, oscillator with the fixed frequency and a lot more.
LM-2575 has many amazing features i.e. it can reduce the heat sink size due to its higher efficiency parameter. In some cases even heat sink is ...
In the modern era, the construction industry stands as a testament to human ingenuity and the relentless drive to build and innovate. From towering skyscrapers to intricate transportation networks, our built environment is a reflection of progress. However, this progress comes at a cost. Every construction project, regardless of its scale, generates waste. If not managed properly, this waste can have significant environmental, economic, and social implications.
The construction industry is one of the largest waste producers globally, with millions of tons of waste generated annually. This waste ranges from concrete rubble and metal scraps to insulation and packaging materials. While some of these materials are recycled or repurposed, a significant portion ends up in landfills, contribut ...
Hi Friends! Hope you’re well. I welcome you on board. In this post today, I’ll discuss What is VPN & How Does it Work?
A VPN stands for Virtual Private Network. It is used to hide your online activities from your ISP (internet service provider) and other third parties. This means you can surf online, share your credentials and send and receive data online with confidence. No one can sneak into your personal data and browsing history. Plus, it gives access to prohibited websites that you cannot see with your regular internet connection. A VPN hides your IP address and replaces it with another string of numbers from another location, which means no one can identify your actual location and IP address. Most companies and individuals use VPN to keep their personal data from the eyes of potent ...
Hello everyone! I hope you all will be absolutely fine ad having fun. Today, I am going to given an elaboration on Introduction to LM833. LM-833 is basically a dual general purpose amplifier. It is usually designed for audio systems. LM 833 is the most common Integrated Circuit (IC) available in the market now a days. This is due to its low cost and high performance activities. It uses bipolar technology.
LM-833 has several different features which make it ideal for general purpose applications. These features include dual supply operation, large input voltage swing, higher gain bandwidth product, higher slew rates, small input offset voltage supply etc. LM- 833 has different real life applications. These application ranges include High Fideli ...
Hello friends, I hope you all are doing great. As we are working on Raspberry Pi libraries for Proteus these days, so today, I am going to share another awesome library i.e. Raspberry Pi Zero W Libary for Proteus. We have already shared the Raspberry Pi Pico, Raspberry Pi 3 & Raspberry Pi 4 Libraries for Proteus, I hope you have already installed these libraries.We have only designed the exterior look of this module, it won't be able to read the Python code. You can use this module to design circuit diagrams of your projects or to demonstrate your project in the presentation. Although, just for fun, we have added the Arduino UNO firmware to it. So, you can add the Arduino hex file in it. Something is better than nothing.So, let's install the Proteus Library and simulate Raspberry Pi Ze ...
Introduction
Hello friends, I hope you are doing very well. Today we are going to learn and practice the master control reset (MCR)! So what is that MCR? Well! This is a tool you might use to control a group of devices with one push button for performing fast emergency responses with one click for a group of devices in one zone. In another word, you divide the program into zones and put this zone between a master control to control their operation as one unit by one contact. This technique is useful for applying emergence stops and also protecting some equipment by applying a safety restriction to not operate when that condition is in effect.
The concept of the master control reset (MCR)
Figure 1 shows the master control relay in a ladder logic showing a couple of rungs between the ma ...
[LM317TEP]
Hello friends, I hope you all are doing great. Today, I am going to share our new online tool which is named as LM317 Calculator. I am quite excited while posting this LM317 Calculator, as I was trying for a long time to post it but couldn't done it because of few problems. Anyways, its here now and is ready to be utilized. Its nothing but a simple LM317 Calculator. I have included two LM317 calculators posted above, one will be used to calculate the Vout while the other will be used to calculate the resistance (R1).
You should have a look at Introduction to LM317, if you don't know much about it. LM317 is an IC regulator which is used to regulate the output voltage and its output voltage is regulated depending on the values of both the resistances attached at its output. He ...
