that day in class we did exercises with the abacus and the teacher did not leave exercises to solve (do not finish) :)well they left us a task, quite long

what is arduino?

Arduino is an open source electronic creation platform, which is based on free, flexible and easy-to-use hardware and software for creators and developers. This platform allows to create different types of microcomputers of a single plate to which the community of creators can give them different types of use.

what is it for?

The Arduino is a board based on an ATMEL microcontroller. Microcontrollers are integrated circuits in which instructions can be recorded, which you write with the programming language that you can use in the Arduino IDE environment. These instructions allow you to create programs that interact with the circuit board.

The Arduino microcontroller has what is called an input interface, which is a connection in which we can connect different types of peripherals on the board. The information of these peripherals that you connect will be transferred to the microcontroller, which will be in charge of processing the data that arrives through them.

The type of peripherals that you can use to send data to the microcontroller depends largely on what use you are thinking of giving it. They can be cameras to obtain images, keyboards to enter data, or different types of sensors.

It also has an output interface, which is responsible for carrying the information that has been processed in the Arduino to other peripherals. These peripherals can be screens or speakers in which to reproduce the processed data, but they can also be other boards or controllers.

features

• Microcontroller: ATmega328

• Operating Voltage: 5v

• Input Voltage (Recommended): 7 - 12 v

• Digital Input / Output Pins: 14 (Of which 6 are PWM outputs)

• Analog Input Pins: 6

• Flash Memory: 32 KB (ATmega328) of which 0.5 KB is used by Bootloader.

• SRAM: 2 KB (ATmega328)

• EEPROM: 1 KB (ATmega328)

• Clock Speed: 16 MHZ.

  Arduino is a free hardware platform, so it is possible to obtain its schematic and its design, in order to do it ourselves, if we wish. Below you will find what is necessary to assemble our own Arduino:

• Files for EAGLE 6.0 or recent versions: Arduino UNO RV 3.0 for Eagle

• Schematic: Arduino UNO Rev. 3.0 Schematic

history

Arduino was invented in 2005 by the then student of the IVRAE Massimo Banzi institute, who, initially, thought of doing Arduino because of a need for learning for the computer and electronics students of the same institute, since at that time, acquiring a micro controller board

What types of sensors are there for Arduino?

As we have told you in the previous paragraph there are many types of sensors for Arduino boards. The best known are:

• 
  
• Temperature sensor
• Humidity sensor
• Light sensor
• Gas sensor
• Atmospheric pressure sensor

As you can see, they are all related to the weather. But there are many others, among them some have been released thanks to mobile devices such as the following:

• Fingerprint sensor
• Voice sensor
• Iris sensor

In addition there are many other types:

• Ultrasonic sensor
• Speedometer sensor
• Vibration sensor
• Empty sensor
• Voltage sensor
• Reflective sensor
• Oxygen sensor
• Pulse or heartbeat sensor
• Optical sensor
• Motion sensor
