First, what is Arduino
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s intended for anyone making interactive projects.
Second, how to buy Arduino
1, can be purchased from authorized Lynx Taobao Jingdong or other electronic business platform. Because this project is open source, so there are many domestic manufacturers did this board, and is relatively inexpensive.
2, of course, cheap board may be problematic. For example, manufacturers of chips with a little time, overall performance is not particularly stable and so on. That the board needs to purchase at their discretion.
3 In addition, because the logo is copyrighted, so if you are not authorized to use the Arduino logo is infringement.
Three, Arduino are all those versions
Fourth, Where can I find information on Arduino
| website | link | description |
|---|---|---|
| Official website | https://www.arduino.cc/ | English |
| community | https://www.arduino.cn/ | Chinese, English is not good for the students more friendly |
Five, Arduino power supply
| Power supply | Supply Voltage Range |
|---|---|
| USB port power supply | 5V, can be used directly USB-powered computer |
| Vin pin power supply | DC 7V~12V |
| 5V power supply pin | A stable voltage DC 5V |
| Power supply circular opening | DC 9V~12V |
Note: For Arduino supply voltage to the right, the voltage is too low, the work of the board will be unstable, easy to burn board voltage is too high.
六、Enjoy！
