Popular Programmable Microcontrollers

Arduino Uno Microcontroller

When you are designing or modifying various projects, it is very important to take general market trends into account. When it comes to microprocessors, it is important to choose not only the most reliable or popular microprocessors but also the tools to work with. We are trying to use all the tools in our DIY projects from Micro-tools.net. There is a lot of information about different types of tools where you can find what suits you the best.

Nowadays, electronics have great potential in programmable microcontrollers. It is certain integrated circuits that allow commands to be executed from a constant voltage source without the help of an external computer. This allows for the development of stand-alone electrical appliances that are indispensable in 21st-century society. Despite the decreasing cost of electronics and the size of transistor chips, most electronic devices still use special purpose microprocessors that are only suited to a specific task.

While mass production is indeed cheaper than general-purpose microprocessors, it is not possible to upgrade or modify the product software. Among other things, the value of the product declines because it is obscene. After all, in these times of rationalization, with the ever-increasing availability of technologies such as the Internet of Things (IoT), platforms are available to create the next generation of smart electronics.

Arduino UNO is a popular microcontroller that electronics enthusiasts love. It is a hobbyist for experimenting, learning the basics of electronics and programming, and creating simple tools. However, it is also used by professionals to develop chip prototypes. Arduino UNO itself is not very useful you have to figure out what to connect to it.

The opportunity is truly unlimited. You can make a simple clock, or you can make any robot. Above all, experiment and bring your ideas to reality to enjoy the process.

Metalworking and Tools for Our Projects

Metal processing has been booming for centuries, but over time, technologies, tools, and equipment differ, making things much easier.

Metal processing

To perform metalworking work, it must be understood that it is not easy. Only having enough skills can do the job properly, and not having the right skills, unfortunately, the results will not be gratifying. You will not need the best benchtop drill press, you will need some more equipment, tools, etc. are also important. If you want to do the metalworking yourself, you may need equipment and tools such as lathes, sheet bending machines, laser cutting machines, measuring tools, work wear and safety equipment, and more.

It is also important to mention that in order to perform different work processes with all these tools and equipment, you need to be able to work with them. When carrying out metalworking work, it is very important that everything goes as it should, and the sequence of work is as follows: heating, normalization, and hardening.

Before that, of course, all the preparatory work takes place, because you need to know what needs to be done from the metal and how to achieve it with all this equipment, so measurements, planning, etc. are needed. To find out more about this, one can only mention that the heating of the metal takes place in such a way that it is heated to the point where it turns red. This is followed by a very slow cooling process.

The metal is then cooled in the air during the normalization process. As we can see, this is not an easy job, so often those who want to do metalworking work entrust them to companies that do it.

Metal cutting is very popular at the moment. This service is being used by more and more people who need to do such work. Of course, it is possible to buy the necessary equipment and cut metal yourself, but usually, such work does not need to be done very much, so it is not worth buying everything to do this work. In this case, Kaunas metal processing is useful.

All you have to do is find the right company to provide these services. True, there are not one and not two of them, so you will have to choose which one is most suitable. Some choose according to the convenience of the place when choosing a company that is close to home or another convenient place where they often stay.

It is also possible to choose according to the range of services offered, as some companies offer a variety of services related to the processing of metal or other materials, which is often very convenient for customers.

Metal cutting

Cutting metal is a complex operation. It consists of two parts: cutting, where the chips are removed from the surface of the metal, or sawdust obtained by sawing it with a saw, and cutting when the metal without chips is divided into parts.

Metal cutting, when chips and sawdust appear, takes place in two ways: manually and by machine. By hand, the metal is cut with a saw, drilled with a hand drill, the metal surface layer is cut with a cutter, threaded with taps and thread cutters, shaved, sanded. The metal is engraved, turned, threaded, drilled and milled on machines and machines.

Cutting a metal without removing chips is its cutting and shearing.

Cutting with a hand-held hacksaw

Learning to use a hand-held hacksaw is easy, but without skills, there are some difficulties: it is difficult to start cutting, it is difficult to hold the frame straight when cutting, not to tilt it sideways, to cut exactly at the marked line, and so on.

Follow these rules when cutting with a hacksaw:

  • start cutting so that the workpiece is immediately touched by three teeth, i. hold the saw at an angle to the workpiece
  • when cutting a wide workpiece, tilt the saw up or down so that a smaller number of teeth touch the metal in the cut, then it is easier to cut;
  • after making a few cuts, check the tape tension; tighten if necessary;
  • insert the workpiece correctly in the clamps: the marked cutting point must be close to the edge of the gills, then the workpiece to be cut will not vibrate;
  • tighten blanks of different profiles in the clamps;
  • cut a thin sheet of metal by placing it between two wooden boards;
  • start cutting in small pushes without pressing the saw, with the thumb of your left hand, from the side, holding the band;
  • if you do not already have the job skills, press a wooden block instead of your thumb;
  • when the cutting bar has cut a small cut and stays in it, cut while holding the saw with both hands, push forward along the entire length of the bar, first pressing harder with your left hand, through the middle of the bar with both hands evenly, and finally harder with the right;
  • finish cutting in short motions by holding the saw with your right hand and holding the end of the workpiece to the left;
  • when cutting a wide part, turn the cutting bar perpendicular to the frame.
  • when cutting, make sure that the incision is at the marking line;
  • when cutting you have to feel how the teeth cut the metal: if when sliding the saw it slips on the metal surface without resistance, then either the teeth of the band are worn or the workpiece is too hard;
  • stop work, check the teeth of the saw by looking at them from above: if the tips of the teeth are shiny, they are worn;
  • if you need to grind or sharpen something use a variable speed bench grinder
  • check the workpiece before cutting: swipe through it with a sharp file, if the file slips, the workpiece is too hard and unsuitable for cutting.

ESP 8266 an Impressive Microcontroller that Supports WIFI


More recently, it took one project to connect an Arduino to the Internet, preferably via WiFi. When I started searching, I didn’t expect what I would find. It turns out that the ESP8266 microcontroller, called system-on-a-chip (SoC), has dominated the market for some time.

This module can connect to 2.4GHz WiFi 801.11 b/g/n protocols and supports WPA/WPA2. In addition, it has an 80 / 160MHz processor, input/output connections (GPIO), 10-bit analog-to-digital converter (ADC), PWM, I2C, SPI, UART and many other awesome but useful things. It also puts you into sleep mode with just 10uA, which allows you to create battery-powered devices.

I think this is a great thing for different kind of DIY projects. Therefore, I would suggest having one in every home, because nobody knows when you will need it for creating something new.

What I liked best was not having to connect it to an Arduino. The good people of the Internet have applied an Arduino programming environment (IDE) to this module and can now write programs directly to ESP8266. Just like a regular Arduino. This requires adding descriptions of the ESP8266 board to the Arduino environment following the instructions on the Internet.

You will also need a separate USB-to-serial adapter to connect the card to your computer (it does not have USB). The following FTDI 232 are recommended:

  • FT232RL
  • CP2102
  • CH340G

It is important to note that the adapter must support 3.3V, not necessarily the ESP8266 used.

What Metalworking Tools Are Used In Industry

In an industry where something is done with metal, metalworking tools are always used as well. They are always necessary because without them there will be nothing – metal is too hard and dense to be machined without special tools. Basically because of that, most things are done with them.

Milling machines

Probably the most important tools for metalworking will always be machines with which it will be possible to bend, cut, engrave, mill. Whether you make small metal products or large constructions, only the machine will always be able to ensure sufficient and proper work.

Folding machines

MachiningWhen working with tinplate, then the metal can be easily bent with special machines. Cabinets, roofing sheets and various products are made with them. Such machines are used in a larger industry rather than in a completely small one.

If the tinsmith is self-employed, he may have one of the simpler folding machines, but not automatic, but for other jobs. The larger the metalworking company, the better it will have machines that can offer multifunctional jobs.

Welding techniques

Also important is the welding technique that determines the bonding of metals. Even the largest industrial structures are welded. Welding is the melting of a metal at high temperatures, when several metals can join together when fused.

Afterwards, they cool down quickly and become perfectly adhered to each other. So the welding technique allows you to do a great deal and quite easily.


If you need a metal pot or a metal pipe, nothing will stick together from the pieces. You will need to get married with special equipment. So, with a lathe, you would be able to run out of metal products.

On the other hand, you would probably look not at yourself, but with the help of someone else. And most likely, you would order metalworking work from someone and have it done for you.

By the way, the labor market shows that there is a severe shortage of people working with metals at the moment. Such work is quite harmful to health and life, especially for welders.

So rarely does anyone want to do their entire career in such an area, even though the salary is actually quite high. However, no matter how harmful it is to health, robots alone do not do this work – they need human hands and strength.
