Currently 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 .
His design is composed to promote the use of electronic engineering in multidisciplinary projectsand for the world of manufacturers of devices and programs, it has become a very useful tool, in relation to free hardware.
On this occasion, we will show you a variety of Features and technical specifications that you should take into account before starting .
Know the most important technical specifications that you should know about the components of an Arduino
With the purpose of simplify design work, Arduino it has some very important characteristics that allow it to carry out work of great determination for anyone who is available.
Keep in mind the most necessary:
microcontroller
The central processing unit It is the fundamental part of an Arduino board, and as its name says, this small circuit is used in a device or a technology project to perform a specific task.
The microcontroller It has communication, input and output ports, this gives it the ability to receive an order that is recorded in its functional blocks from the computer, and then carry out a function. In general, the most used microcontrollers are the Atmel AVR, as well as the Atmega168, Atmega328, Atmega1280, and the Atmega1280. On the other hand, the orders for this circuit are transmitted through the implemented in your .
Voltage
The voltage in this field is known to be the power source of a Arduino Y usually only requires a voltage of 5 volts to work. There are several methods to power it properly so that it doesn’t cause any error or failure later on.
Power adapter
The power adapter It is one of the most frequent uses to maintain an Arduino steady, the recommended voltage is 7-12 V, and a maximum is 6-20V, depending on the Arduino and the sufficient power required. A great choice for projects that have a plug nearby and don’t need to be moved.
USB
This is another of the most common ways 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 sources
The Using batteries or external sources is another way to sustain an Arduino.However, they have a short duration respectively due to their short current capacity. Its consumption can reach from 300 to a total of 500 mA~1 A.
Number of Pins
In electronics, a pin is known to carry electricity from one component to another. An Arduino board is made up of a group of pins of entrance exit that work to connect different expansion boards and microcontrollers. These Pins are used to be programmed by the integrated development environment (IDE), and are powered by a USB type B cable, or a 9V battery. Commonly a board is supplied by 14 digital pins Y 6 analog pins
digital pins
The digital pins are numbered 0 through 13 and They have an input and output configuration. working only with values High and low. These digital inputs are specialized to receive voltage signals.
The corresponding voltage for an input pin is 0 to 5 volts, thus achieving better performance and We prevent the Arduino board from being damagedfor that reason, a voltage higher than the allowable one must not be applied. According to the recommended operations, these pins work with Pull Down and Pull Up resistorswhen in idle 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. Opt for a resolution of 0 to 1023 different values, so these inputs are known to be much more expensive and limited than digital inputs. Analog signals are measured by taking any value within the range of -Vcc and +Vcc.
Therefore, to measure these signals, an analog-to-digital converter is required, which is in charge of converting analog measurements into digital measurements encrypted with the number of bits. This means that analog pins can be used for many more tasks than digital ones. Among the examples of analog input connections, there is 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 have an oscillatora tool that helps to verify the process and performance that such a project is running.
That is to say, that the oscillator is in charge of counting time. The internal clock speed of the Arduino UNO board is 16 MHz, which is read at 16 million clock pulses per second. However, it is worth mentioning that the Arduino operation has to be in accordance with an execution time, therefore, the higher the clock speed, the better results will be obtained.
RAM memories
sram memory acts as a storage unit, Therefore, it is very similar to a RAM memory of a CPU. This dynamic and random access memory is used for the processes carried inside a microcontroller. its development It was specialized to keep data while it is poweredthis means, that if your source of support is interrupted, can be reached lose the information.
However, it is a fundamental factor for short consumption and advantageous data handling. When we refer to a random access to a memoryit means that the locations that are in it can be written or read in any order. For this reason, it is that the memories SRAMs They are much more expensive and efficient.
Flash memory
In this field of electronics, Flash memory has one of the most crucial tasks to design a project. Its capacity may vary according to the Arduino model used. Flash memory is very similar to SD cards or a Pendrive, since, Allows you to store the programming code.
This means that, to avoid failures in relation to different functions of the Arduinoit is necessary to count with a good capacity Flash memory. Another characteristic of these memories is their high efficiency in saving data and codesbecause their design allows them to preserve the information, in case the Arduino turns off.
List of the best Arduino kits and boards for beginners that you must know to develop your own devices
Based on the technical specifications provided by an Arduinoyou can consider having a support team to create unique devices.
For this reason, we present some of the most used Arduino kits and boards so that you can undertake projects to your liking:
