Practices, Exercises, and Code Examples With Arduino Uno (MIC026E)

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.

Histeresis (ART376E)

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.

Antenna Amplifier (ART411E)

  This circuit helps to increase the intensity of signals picked up by an antenna before being brought to the receiver. It is designed to operate with signals between 200 kHz and 30 MHz, which corresponds to the range of medium waves and short waves. The current demanded by this circuit is extremely low, so the battery life used in your power supply is very great. The signals are applied to the base of a transistor and removed from its collector.

Parabolic Microphone (ART377E)

Ultra-sensitive directional microphones can be used in many interesting practical applications. One is spying, when we focus on people talking at a distance and we can hear everything they say. Another is in the recording of sounds of nature and finally we have the possibility of installing the system in a robot for detection of remote sounds. See in this article how you can build a simple parabolic microphone using common components.

CMOS Logic Test (ART378E)

In the analysis of digital logic circuits, it is fundamental to have a logical level analyzer. However, if a sophisticated instrument with multiple inputs and the possibility of dynamically analyzing a circuit is not available, a logical probe may be useful. In fact, a probe can complement the use of an analyzer by doing parallel tests independently. The probe we describe works with voltages from 3 to 15 V and has a very high input resistance.
