Arduino – under this name combined a few popular printed circuit boards, which have standardized the location of all the findings for microcontrollers, as well as the same dimensions within a single product model. Some of them have additional elements, for controlling the voltage of power supply and USB, which thanks to its versatility can be recharged and charge, and be used for communication microcontroller with PC. One of the best variations of the family of these boards is the Arduino UNO R3 model.
Almost all visible terminals are connected directly with the microcontroller. Some of them may be available to connect to, and involved in the internal schema. The USB outlet can be used to supply power voltage of 5 V and also for the exchange of information with the computer, which in this case recognise the device as non-simultaneous serial port. On the technical side, for the microcontroller and the computer to "chat" with him is also an asynchronous serial port, through which data exchange is taking place. Connect Arduino UNO R3 with your hands-simple, then the main snags is to understand how the process of data exchange, what are its features. About it you can read on.
Operating voltage is 5 V. But the input for the external power supply is designed for 7-12 V. it has been Experimentally established that minimum enough voltage 6 V, and the maximum that the Board can withstand is 20 V. But it is better not to deviate from the recommended settings to avoid unwanted situations, such as failure and similar options that are dependent on the supply voltage
The introduction is over. Additionally, if you need some of the easy operation Arduino module board, you could purchase at Banggood, which is the wholesale platform to provide you the low prices. Such as, i2c lcd display, jewelry digital scale, etc.
