One of the most important phenomena we observe in magnetic materials is hysteresis. Knowing exactly what it means is essential for everyone working with inductors and transformers, especially in modern circuits such as switched-mode power supplies, frequency inverters and AC / DC converters. In this article, we review the basic concepts of magnetism and explain what hysteresis is.
This circuit maintains constant charge of an accumulator and in the event of a power failure a 12V lamp lights up. The circuit is very simple and with the use of a battery of 6 amperes / hour a 12V x 500 mA lamp will remain lit for 12 hours.
Microcontrollers are part of any modern electronic devices, from radios, cell phones, toys, industrial, medical, navigation, control devices, etc. Knowing and practicing with them is very useful for the development of electronic systems. The Arduino platform allows us to easily present ourselves in the world of microcontrollers and their applications. In this article, we'll look at the most common codes in the world of microcontrollers and Arduino. Buttons and LEDs are the most common electronics in any circuit and it is important to know how to program them.

In recent years, the Arduino development platform has grown remarkably. This was due to its easy handling, hardware and software contributions and interest from companies such as Intel, Microsoft, Texas Instruments, etc., in adapting their products to this platform. One of the most used boards is Arduino Uno, whose core microcontroller is Atmega328p. In this article, we will learn about its internal capabilities and microcontroller architecture, which are very useful when designing electronic systems.

Are spirits or goblins trying to get in touch with humans? Are extraterrestrials trying to get in touch with the inhabitants of this planet? Or, Is it simply a defect of a transmitting equipment? The strange radio transmissions captured by Bart and Bert and analyzed by Professor Ventura lead our heroes to a “chilling” adventure and some confusion in the peaceful Lemon city!

Here is an interesting assembly for those interested in robotics, electronic toys and other curiosities, but do not have the resources to carry out a very complicated project. It is a mini-robot which sees obstacles and luminous objects through two phototransistors used as "eyes". These Phototransistors send the information to the robot's "mini-brain" that guides it in the direction of looking for the clearest places.
