The Arduino community is a huge number of users, a lot of training materials, projects and turnkey solutions that are used in various applications. The company also offers a very simple method of interacting with external peripherals. Initially, the Arduino base was designed to provide a variety of actuators and sensors to the microcontroller without the use of additional circuits. The development of simple devices and applications does not require in-depth knowledge of electronics.
Device description
Arduino Uno is an open platform that allows you to assemble a variety of electronic devices. This board will be useful and interesting to creative people, programmers, designers and other inquisitive minds who like to design their own gadgets. Arduino Uno can work both in conjunction with a computer, and autonomously. It all depends on the purpose and idea.
The Arduino Uno platform consists of software and hardware that are highly flexible and easy to operate. For programming use a simplified version of C ++ (Wiring). Designing can be carried out on free Arduino IDE software and on the basis of arbitrary C / C ++ tools. The device supports Linux, MacOS and Windows operating systems. For programming and communication with a computer, a USB cable is used, and for working in stand-alone mode , a power supply unit (6-20V) is required. For beginners, ready-made kits for electronics design have been developed - the Matryoshka series.
Arduino Uno R3
This is a new model made in Italy. It is based on the ATmega328p microprocessor, whose clock frequency is 16 MHz, memory - 32 kb. The board has 20 contacts (controlled) output and input, designed to interact with peripheral devices.
Device features
Arduino Uno is capable of interacting with other Arduino, computers and microcontrollers. The device platform allows for a serial connection using the contacts RX (0) and TX (1). The ATmega16U2 processor broadcasts such a connection via a USB port: as a result, an additional virtual COM port is installed on the computer. Arduino software includes a utility that exchanges text messages over a created channel. The RX and TX LEDs are installed on the device board, which are lit during the transfer of information between the computer and the ATmega162U processor. Thanks to a separate library, you can organize a connection using various contacts, not limited to zero and first. And with the help of additional expansion cards, it becomes possible to organize other methods of interaction, for example, Wi-Fi, a radio channel, an Ethernet network.
Arduino Uno smd has a special fuse that protects the computer's USB ports from short circuits and overvoltages. Although computers have their own protection, a fuse provides added confidence. It is able to disconnect if more than 500mA current is supplied to the USB port input, and restores it when the current returns to normal.
Conclusion
Summing up, let's say that Arduino is a very flexible and functional platform for developing various applications. It has tremendous potential for interfacing with peripheral devices. Arduino is great for studying microcontrollers, and can also serve as the basis for small projects.
