There have been numerous incidences of teenagers killing themselves with a gunshot, a shooter perpetrating mass violence, or a family member accidentally shooting another. These cases have occasionally brought about discussions about “smart gun” technology.
The discussion of smart gun technology started in 1995 in the NIJ (National Institute of Justice), where a technological approach was recommended to reduce the number of incidents where police officers were killed by assailants who grabbed guns. In the recent years, we have also seen leaders like Barack Obama recommending the commercialization of tech-gun safety systems.
What is smart gun safety?
The phrase smart gun is adopted by the society at large as a form of a personalized electronic safe ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at 3 Engineering Gadgets To Invest In This Year. At present, there are more than 1.6 million engineers employed in the USA, according to the U.S. Bureau of Labor Statistics. As we become increasingly reliant on technology, engineers will become progressively more important, and more students will study towards a suitable qualification.
Although the engineering field is immensely diverse, there is one thing that every engineer is in need of – a set of useful tools and gadgets to help them solve problems, create prototypes, create advanced technologies, and even explore new worlds. Here is a closer look at three engineering gadgets well worth investing in this ...
Social media has become an integral part of our daily lives, connecting people from different corners of the world, sharing experiences, and shaping cultural trends. Over the past decade, various platforms have emerged, each leaving its mark on the ever-evolving landscape of social media technology. In recent years, TikTok has emerged as a dominant force in the social media realm, not only redefining the way we consume and create content but also influencing the future of social media technology.
TikTok, launched in 2016 by the Chinese company ByteDance, has rapidly gained popularity, amassing billions of users worldwide. Its unique short-form video format, where users can create and share 15 to 60-second video clips, and to get TikTok likes
, has revolutionized the way we engage with ...
Hello everyone, today I am going to share Stepper Motor Control using PIC Microcontroller. We are all quite well aware of stepper motor but if you don't have much of the idea about this motor then you should give it a google search. :P Stepper motor is used in such projects where precise movement is required. Projects where we need to move the object at some particular angle. Stepper Motor works on electromagnetic phenomena. Electromagnets are present in the stepper motor and when we supply voltage across them, these electromagnets got polarized and produce a magnetic field and in order to depolarize them, what we need to do is simply depolarize these electromagnets. We all know that in motors, we have rotor and stater so in stepper motor these el ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of you about how to make a simple program for DC Motor Direction Control using Arduino. The word DC is basically an abbreviation of Direct current. So, a direct current motor is commonly used motor having two input terminals, one is positive and the other one is negative. If we connect these terminals with the voltage supply the motor will rotate. If you change the polarity then motor will rotate in opposite direction. You should also have a look at Difference between DC & AC Motors to get a better idea about these motors.
DC motor has a lot of applications. You can use it in automation projects, for controlling static as wel ...
Hello friends, I hope you all are doing great. In today's tutorial, I am gonna show you How to Choose and Set Up a Business Phone System. Normally engineers like to be an entrepreneur and if you wanna start your own business then its essential to have a Business Phone Number. To maintain the success of your business, having a relevant and structured phone system will help your business grow. Here are the ways on how to choose and set up a business phone system.
Choosing Your Business Phone System
Before you can begin setting up, it is important that you take the time on choosing what type of phone system works for you. If you are starting a new or small business, every call you receive is important and could be the make or break to the success of y ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a new project which is Receive SMS with Sim900 & PIC Microcontroller using AT Commands. I have already posted this same project on Arduino named as Receive SMS with AT Commands using Sim900 & Arduino. In that project, I have interfaced SIM900 module with Arduino but today I am gonna interface it with PIC Microcontroller.
I have also designed a GSM Library for Proteus using which you can easily now simulate your SIM900D module in Proteus. Sim900 Module is used to send and receive SMS and it is widely used in automation and security projects. I have also posted another Project in which I have designed the Proteus simulation of GSM based Home Sec ...
Welcome to the next tutorial of our raspberry pi programming tutorial. The previous tutorial showed us how to set up a weather station using the Internet of Things (IoT) on a Raspberry Pi 4. First, we studied how a weather station works on a fundamental level. Then we developed a Python script to collect data from the station. In contrast, we'll construct an automatic gate using a Raspberry Pi, a load cell, and an HX711 weight sensor.
These pressure-sensitive gates are common in shopping centers and showrooms; they open when someone is in the immediate vicinity and close again when the person is out of sight. Like the Automatic Gate, we just made, this one will open in response to weight or pressure and stay that way until the force is removed. If ...
Hello friends, hope you all are fine and having good health. In today's post, I am going to share an Ultrasonic Sensor Library for Proteus. A few days ago, I posted a tutorial on Arduino Library for Proteus, and today I am going to share the new Ultrasonic Sensor Library for Proteus. Using this library, you can easily interface Ultrasonic Sensors with different Microcontrollers like Arduino, PIC Microcontroller etc.First of all, let's have a brief introduction to ultrasonic sensor. In an ultrasonic sensor, there are two nodes available, one is the transmitter while the other is the receiver. The transmitter sends an ultrasonic wave and this wave strikes any hindrance present in front of it and then bounces back. This bounced ultrasonic sensor is th ...
Hello everyone I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge on Introduction to TL494. It supports all of the functions that are necessary for the Pulse Width Modulation (PWM) control circuits. Power supply control is the basic purpose of the TL494 device. It has an output control circuit, a flipflop, dead time comparator, two different error amplifiers, 5V reference voltage, oscillator and a PWM comparator. TL 494 operates properly between the frequency of 1kHz to 300kHz.
The Dead Time Comparator (DTC) provides around 5% of dead time. Both of the error amplifiers display a common-mode voltage from -0.3V to (Vcc-2)V. If we provide a sawtooth wave at the CT terminal and terminate RT to the referenc ...
