Introduction to Arduino
What is Arduino?
Arduino is an open source code based on the Simple i / o platform, and has a similar use Java, C language Processing / Wiring development environment, easy to understand features. So you can quickly use the Arduino to make things interesting. Arduino can use with a number of electronic components such as: LED lamp, buzzer, keypad, light-sensitive resistors and the like. Arduino development environment interface is based on open source principles, it allows you to download free of charge to develop more amazing interactive work.
Open the original schematic design, interface development software free download, also follow their own needs to be modified, download the program is simple and convenient. Simply use the sensors connected to a wide variety of electronic components (such as: LED lamp, buzzer, keypad, photoresistor, etc.), make a variety of interesting works.
High-speed micro-processing controller (ATMEGA328), user interface and development environment is very simple, easy to understand, very suitable for beginners to learn.
Digital I / O digital input / output terminal of 0 to 13.
Analog I / O Analog inputs / outputs of 0 to 5.
Support ISP download function.
Input voltage: No external power supply when connected to the computer USB, external power supply 5V ~ 9V DC voltage input.
Output voltage: 5V and 3.3V DC output voltage DC output voltage.
Using Atmel Atmega328 microprocessor controller
