Arduino is an easy-to-use, easy-to-use open source electronic prototyping platform. Includes hardware (various models of Arduino board) and software (ArduinoIDE). Developed in the winter of 2005 by a European development team. Its members include Massimo Banzi, David CuarTIelles, TomIgoe, GianlucaMarTIno, DavidMellis and NicholasZambetTI. It is built on the open source simpleI/O interface and has a Processing/Wiring development environment similar to Java and C. There are two main parts: the hardware part is the Arduino board that can be used for circuit connection; the other is ArduinoIDE, the program development environment in your computer. As long as you write the program code in the IDE and upload the program to the Arduino board, the program will tell the Arduino board what to do. Arduino can sense the environment through a variety of sensors, feedback, influence the environment by controlling lights, motors and other devices. The microcontroller on the board can be programmed in Arduino's programming language, compiled into a binary file, and burned into the microcontroller. Programming for Arduino is done through the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino-based projects can include only Arduino, or Arduino and other software running on a PC, communicated between them (such as Flash, Processing, MaxMSP). The Arduino driver is located under the drivers folder under ArduinoIDE. If you haven't downloaded ArduinoIDE yet, please download it first. You can download it from Baidu or on the official website. The latest version is 1.6.xx; the latest version of ArduinoUNO, ArduinoMEGA, ArduinoLeonardo Such controllers and compatible controllers of various manufacturers, under MACOS and Linux systems, do not need drivers, you only need to plug directly, you can use. But on Windows systems, you need to install the driver configuration file for Arduino to drive Arduino normally. Plug in the Arduino board, the computer will display in the lower right corner, wait a while, Successful, will show, the installation is complete; Failure, will display, "Failed to install the drive device successfully"; Right click on "My Computer", Device Manager, other devices; Double-click the device and select "Update Driver"; Select the second item, "Browse your computer for driver software"; Enter the driver address, which is the path of the driver in the AeduinoIDE you downloaded; During the installation process, the following prompt will appear, choose to always install this driver; The system prompts that the driver is successfully installed. In the device manager, you can see the COM port of Arduino; Banknote Value Counting Machine One CIS Banknote Value Counting Machine,Banknote Value Counting Machine One CIS,Banknote Value Counting One CIS Machine Suzhou Ribao Technology Co.
