Today the arduino board it has become very popular among many developers from different parts of the world, and this is because, Anyone can use it to easily develop hardware and open source software.
His design It is designed to promote the use of electronic engineering in multidisciplinary projectsAnd for the world of device and software manufacturers, it has become a very useful tool in relation to open-source hardware.
This time, we'll show you a variety of Features and technical specifications you should consider before starting working with Arduino projects.
Learn about the most important technical specifications you should know about the components of an Arduino
With the purpose of simplify the design work, Arduino It has some very important characteristics that allow it to perform highly demanding tasks for anyone who is willing to do them.
Keep in mind the most necessary ones:
Microcontroller
La central processing unit It is the fundamental part of an Arduino board, and as its name suggests, This small circuit is used in a device or technology project to perform a specific task.
El microcontroller It has communication ports, input and output, which gives it the ability to receive an order that is recorded in its functional blocks from the computer, and then carry out a function. Generally, the most commonly used microcontrollers are the Atmel AVR, as well as the Atmega168, Atmega328, Atmega1280, and the Atmega1280. On the other hand, the commands for this circuit are transmitted through the programming language for Arduino implemented in its Arduino IDE.
Voltage
El voltage In this field, it is known for being the power source of a Arduino y It usually only requires a voltage of 5 volts to operate. There are several methods to feed it properly, so that it does not cause any errors or failures later on.
Power adapter
El power adapter It is one of the most frequent uses for maintaining an Arduino stable, The recommended voltage is 7-12V, and the maximum is 6-20V, depending on the Arduino and the power requirements. It's a great choice for projects that have a power outlet nearby and don't need to be moved.
USB
This is Another common way to power an ArduinoIt provides a total output current of 500mA, because a USB cable is used to connect it to the computer.
Batteries or external power sources
El Using batteries or external power sources is another way to power an ArduinoHowever, they have a short lifespan due to their low current capacity. Their consumption can range from 300 to 500 mA to 1 A.
Number of Pins
In electronics, a pin is known for carrying electricity from one component to another. An Arduino board is made up of a group of pins. pines de entrance exit These pins are used to connect different expansion boards and microcontrollers. They are programmed by the integrated development environment (IDE) and are powered by a USB Type-B cable or a 9V battery. A board is supplied by 14 digital pins y 6 analog pins
Digital Pins
The digital pins are numbered from 0 to 13 and They have an input and output configuration, working only with values HIGH and LOWThese digital inputs are specialized in receiving voltage signals.
The corresponding voltage for an input pin is 0 to 5 volts; this way, better performance is achieved and We prevent the Arduino board from being damaged., for that reason, The voltage applied must not exceed the permitted level.According to the recommended operations, these pins They work with Pull Down and Pull Up resistances, when they are in an inactive state, to distinguish the voltage value from high to low.
Analog pins
Analog inputs They are classified from A0 to A5 to facilitate their recognition. It offers a resolution of 0 to 1023 different values, which is why these inputs are known to be much more expensive and limited than digital ones. Analog signals are measured by taking any value within the range of -Vcc and +Vcc.
Therefore, measuring these signals requires an analog-to-digital converter, which converts analog measurements into digital measurements encoded with a number of bits. This means that Analog pins can be used for many more tasks than digital pins. Examples of analog input connections include the potentiometer, where the output voltage can be read and removed by the equipment.
Clock speed
Mainly Projects that are carried out with integrated circuits include an oscillator, a tool that helps verify the process and performance that the project is running.
That is, the oscillator It is in charge of counting time. The internal clock speed of the Arduino UNO board is 16 MHz, This translates to 16 million clock pulses per second. However, it's worth noting that Arduino's operation depends on a specific execution time; therefore, the higher the clock speed, the better the results.
RAM memories
SRAM memory It acts as a storage unit, Therefore, it is very similar to the RAM of a CPU. This dynamic, random-access memory is used for the processes carried out within a microcontroller. Its development It was specialized to preserve data as long as it is poweredThis means that if your source of income is interrupted, one can reach losing the information.
However, it is a fundamental factor for low power consumption and advantageous data management. When We are referring to random access to memory., means that the locations found within it They can be written or read in any order.That is why the memoirs SRAMs They are much more expensive and efficient.
Flash Memory
In this field of electronics, Flash memory has one of the most crucial tasks in designing a projectIts capacity may vary depending on the Arduino model used. Flash memory is very similar to SD cards or USB flash drives, since It allows you to store the programming code.
This means that, to avoid errors related to different Arduino functionsIt is necessary to have with a high-capacity Flash memoryAnother feature of these memories is their High efficiency when storing data and codesbecause their design allows them to retain information in case the Arduino turns off.
List of the best Arduino kits and boards for beginners that you should know about to develop your own devices
Basado en the technical specifications provided by an ArduinoYou might consider having a support team to create unique devices.
For this reason, we present some of the most popular Arduino kits and boards so you can undertake projects to your liking:
