Vehicle Tracking systems are very commonly used in fleet management and asset tracking applications. Today these systems can not only track the location of the vehicle but can also report the speed and even control it remotely. In general, tracking of vehicles is a process in which we track the vehicle location in form of Latitude and Longitude (GPS coordinates).…
The objective of this project is to convert 220V AC supply in to +12V and -12v DC supply, that is why it is named Dual Power Supply as we get positive and negative 12v power supply at the same time.
This can be achieved in simple three steps:
Firstly, 220V AC is converted into 12V AC by using simple step-down (220V/12V) transformer. Secondly, output of this transformer is given to…
We are living in the era of 5G and 5G-enabled devices; however, old technologies like the walkie-talkie system and RF communication system are still paramount in scenarios where a remote, short-distance, cheap, and low-cost communication is required. For example, if you have a building or heavy-weight bearing construction company, then your workers need to communicate with…
We all know about Electricity energy meters which are installed in everyone’s house or offices to measure the electricity consumption. At last of every month, many of us get worried about the high electricity bill and we have to look at the energy meter once in a while. But what if we can monitor our electricity uses from anywhere in the world and get an SMS/E-mail when your…
In the previous parts(Part 1, Part 2, Part 3) of this project, we investigated different aspects of our smart watch projects and learned to integrate and test each individual part. In this we are going to use what we have learned to create our own smartwatch from scratch, using a combination of hardware and software components. Throughout…
In many of our previous articles, we have used many different types of temperature and humidity sensors like DHT22, DHT11, DS18b20, and LM35 to measure environmental parameters. In every one of those articles, the one thing in common is that none of those sensors measure barometric pressure. So in today's article, we wanted to interface the BMP280 with an Arduino and measure…
In the Internet, all the websites are hosted on a computer and this computer is called a server. Since this particular server is used to serve web pages and web requests, we call it a web server. Instead of using a computer, we can also use an ESP32 to respond to web requests, thanks to the ESP32’s built-…
You must have seen someone speaking on the MIC and the amplified voice coming from the speaker, how this is possible? Is there any circuitry between MIC and speaker of we can directly connect Microphone with speaker to get it working? In this circuit, we learn to build a simple Microphone to Speaker system, in which input sound is given to the MIC and we hear the amplified…
Styrofoam and polystyrene have been one of the most efficient methods of model making amongst the maker community, thanks to their lightweight, extremely low cost, and the ease with which they can be crafted into some breathtaking pieces of artwork.
But working with Styrofoam often requires a lot of heated element tools that get…
Today, our desks are full of devices that require connection to be connected with the PC via USB, or we need to work with multiple devices that have USB ports. It became a problem as Laptops lack multiple ports, and this is where a USB hub or USB Port Extender comes in handy. This comprehensive guide demonstrates how to build a professional DIY USB hub with a power supply using…
The DHT22 temperature and humidity sensor is a versatile and cost-effective sensor used to measure ambient temperature and humidity for a wide range of applications. It is based on a digital signal output and can provide high-accuracy measurements with a resolution of 0.1 degrees Celsius for temperature and 0.1% for humidity. The sensor uses a capacitive humidity…
There are lots of microcontrollers available from reputed companies such as PIC, Texas Instruments, ST and the list goes on. But when we differentiate those microcontrollers with form factor vs features vs price, it gets hectic to choose one. However, nuvoton is a Taiwan based semiconductor company that was spun-off as a Winbond affiliate in 2008. The company offers very…
