Arduino Uno: Appointment, Platform Description

The Arduino community is a huge number of users, a lot of training materials, projects and ready-made solutions that are used in various applications. Also the company offers a very simple method of interaction with external peripheral devices. Initially, the Arduino base was designed to provide connection of various actuators and sensors to the microcontroller without using additional circuits. The development of simple devices and applications does not require deep knowledge in 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 for creative people, programmers, designers and other inquisitive minds who like to design their own gadgets. Arduino Uno can work both in conjunction with the computer, and autonomously. It all depends on the purpose and the idea.

Platform Arduino Uno consists of software and hardware parts, which are very flexible and easy to operate. For programming use a simplified version of C ++ (Wiring). The design can be performed on the free Arduino IDE 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 a stand-alone operation a power supply unit (6-20V) is required. For beginners developed ready-made sets for designing electronics - a series of "Matryoshka".

Arduino Uno R3

This is a new model produced in Italy. It is based on the microprocessor ATmega328p, whose clock frequency is 16 MHz, memory - 32 kb. The board has 20 contacts (monitored) output and input, intended for interaction with peripheral devices.

Features of the device

Arduino Uno is able to interact with other Arduino, computers and microcontrollers. The device platform allows serial connection using the RX (0) and TX (1) terminals. The ATmega16U2 processor translates such a connection via a USB port: as a result, an additional virtual COM port is installed on the computer. The Arduino software includes a utility that exchanges text messages on the created channel. The device board is equipped with RX and TX LEDs, which light up during transfer of information between the computer and the ATmega162U processor. Thanks to a separate library, you can organize a connection using different contacts, not limited to zero and first. And with the help of additional expansion cards, it becomes possible to organize other ways of interaction, for example, Wi-Fi, a radio channel, the Ethernet network.

Arduino Uno smd has a special fuse, which protects the USB-ports of the computer from short circuits and overvoltage. Although computers have their own protection, the fuse provides additional confidence. It is able to break the connection if more than 500 mA is applied to the input of the USB port, and restores it when the current returns to normal.

Conclusion

Summing up, we will say that Arduino is a very flexible and functional platform for developing various applications. It has great opportunities to provide interaction with peripheral devices. Arduino is great for studying microcontrollers, and can also serve as a basis for small projects.
