RFID (Radio Frequency Identification) is a way to ensure the storage and transmission of information from a convenient label carrier to the desired location using special devices. Such identifier tags make it easier to recognize various objects: goods in the store, mobile vehicles during transportation, help determine their location, can identify people and animals, not to mention the wide possibilities of identifying documents and property.

The electromagnetic wave received by the RFID tag from the antenna activates it, and it becomes possible to write data to the tag and read data from the tag. The antenna thus serves as a multifunctional communication channel between the transceiver and the tag, which fully ensures the processes of data transmission and reception. Antennas of various shapes and sizes can be built into scanners, gates, turnstiles, - in different means for working with RFID ...

The New Year is coming soon! On the shelves of stores next to tangerines, sweets and champagne, Christmas toys appear: colorful balls, tinsel, all kinds of flags, beads and, of course, electric garlands. Perhaps the usual garland of multi-colored light bulbs cannot be bought. But various flashing lights, mainly of Chinese manufacture, simply can not be counted. Microscopic bulbs can be placed on a piece of cardboard or woven into a carpet of wires, which can decorate an entire window immediately.

Christmas tree garlands are also very diverse, especially the external design, design. The cost of such garlands is small, as, in fact, the power of the bulbs. Most garlands have a small plastic box with one button, a cord with a power plug and wires going to a garland of colorful lights. Garland design can be the most diverse. ...

Do you want to master the modern field of electronics and learn how to program microcontrollers? There is everything to start developing your own electronic devices on microcontrollers yourself - the author’s video course "Programming Microcontrollers for Beginners".

Who is this course for? First of all, I created it for beginners, for those who are already familiar with the basics of electronics and programming, who know basic electronic components, assemble simple circuits, know how to hold a soldering iron and want to go to a whole new level, but constantly postpones this transition because difficulties in mastering new material.

The course is perfect for those who have just recently made their first attempts to learn microcontroller programming, but are ready to give up everything because it doesn’t work or works, but not as it needs to (is it familiar ?!). The course will be useful to those who are already collecting ...
