Details:
This section Arduino UNO R3 is the latest version, the interface chip consists MEGA8U2 upgraded to MEGA16U2, also changed the interface design, increasing the SDA and SCL interface.
Arduino is an open-source code base with the Simple i / o platform, and with the use of a similar java, C language development environment. So you can quickly use the Arduino language software such as Flash or Processing ... make interactive work. Arduino developed can be used such as electronic components or other controllers Switch or Sensors, LED, stepper motors or other output device. Arduino can also operate independently with the software can be a communication platform, for example, said: flash processing Max / MSP VVVV or other interactive software ..., Arduino development IDE interface is based on the principle of open source that allows you to download free of charge to develop more so Surprisingly interactive work.
Power Design
Arduino-powered systems have two options, USB direct power supply or an external power supply. Power supply will automatically switch selection. Optional external power supply AC-to-DC adapter or the battery, the limit of this voltage range of panel 6V ~ 12V, but if the supplied voltage is less than 6V, I / O port may not be supplied to the voltage of 5V, so there will be no stable; event provides a voltage greater than 12V, regulator device then there could overheat protection, are more likely to damage the Arduino. Therefore, the recommended operating supply of 6.5 ~ 12V, recommended power supply is 7.5V or 9V.
Technical Specifications:
1. Digital I / O digital input / output of 0 to 13.
2. Analog I / O Analog input / output of 0 to 5.
3. Support USB interface protocol and powered (no external power supply).
4. Support the ISP download function.
5. Supports MCU TX / RX terminals.
6. Support USB to TTL TX / RX terminals.
7. Support AREF pin.
8. Support 6 groups PWM pin (Pin11, Pin10, Pin9, Pin6, Pin5, Pin3).
9. Input voltage: no external power supply when connected to USB or external 7V ~ 12V DC input.
10. Output voltage: 5V DC output and 3.3V DC output and external power input.
11. Using Atmel Atmega328P-PU microcontroller.
12. Arduino sizes: Width 70mm X height 54mm.
Features:
1. Open source schematic design, program development interface free download, modify their own needs also follow!!
2. Arduino ISP download cable can be used, the new IC process of self burned into "bootloader";
3. Can be based on the official circuit, simplifying the Arduino module, complete the independent cloud for the microprocessor controller;
4. The sensor can be simply, a variety of electronic components are connected (such as: infrared, ultrasonic, thermal, light dependent resistor, servo motor, etc.);
5. Support a variety of interactive programs such as: Flash, Max / Msp, VVVV, PD, C, Processing, etc.;
6. Use low-price microprocessor controller (ATMEGA328P-PU);
7. USB interface, no external power supply, 500mA resettable fuse to avoid your computer USB power overload, and another to provide 9VDC input interface;
8. Applications, the use of Arduino, a breakthrough in the past can only use the mouse, keyboard, CCD input devices such as interactive content, you can more easily reach a single or multiplayer interactive games
