In addition to the development board of Raspberry_pi before, in addition to the powerful Raspberry_PI development board, many of our electronic enthusiasts will also choose Arduino development board to do their own small production or program design, then Arduino is what, he has What a powerful charm is dumped with electronic enthusiasts at home and abroad. Let me take everyone to enjoy it.
Introduction to Arduino
Arduino, is an open source-based USB interface SIMPLE I / O interface board (including 12-channel digital GPIO, 4 channel PWM output, 6-8 channel 10bit ADC input channel), and has IDE integration using similar Java, C language Development environment.
Let you quickly use the Arduino language with Flash or Processing ... and other software to make an interactive work. Arduino can use the development of electronic components such as Switch or Sensors or other controllers, LEDs, stepper motors, or other output devices. Arduino can also operate independently as an interface that can be with the software trench, such as: Flash Processing Max / MSP VVVV or other interactive software.
Arduino Development IDE interface is based on open source code, allowing you to download more amazing interactive works for free download.
Advantages of Arduino
1. Circuit diagram design of open source code, program development interface free download, you can also modify it yourself!!
2. Use a low price microprocessor controller (atmega8). It can be powered by USB interface and no external power supply. You can also use external 9VDC input.
3, Arduino supports ISP online, you can burn new "bootloader" firmware into the ATMEGA8 chip. After bootloader, you can update the firmware via the serial port or USB TO RS232.
4, can simplify the Arduino module to complete the Microprocessor Control of Independently Operations in accordance with the EAGEL format PCB and SCH circuit maps provided. Connect with sensors, all kinds of electronic components (EX: infrared, ultrasonic, thermistor, photosensitive resistance, servo motor, ..., etc.)
5, support a variety of interactives, such as flash, max / msp, vvvv, pd, c, processing ..., etc.
6. Application, using Arduino, breakthrough in the previous use of the interactive content of the device entered by the mouse, keyboard, CCD, can be more simply reached interaction with single or multiplayer games.
ARDUINO's core chip --ATmega8
Atmega8 is an 8-bit microcontroller based on AVR RISC structure produced by low power CMOS processes. The core of the AVR microcontroller is to associate 32 working registers and rich instructions, all of which are directly connected to the ALU (arithmetic logic unit), implementing an instruction performed in a clock cycle (reading and writing) ) Operation of two independent registers. This structure improves code efficiency so that most of the execution time of most instructions is only one clock cycle. Therefore, ATMEGA8 can reach close to 1MIPS / MHz performance, 10 times higher than the normal CISC microcontroller.
Why is Arduino so popular?
First, Arduino focuses on flexible use, which avoids the complexity of unnecessary industrial hardware and software technology. Nothing to see a 12-year-old boy demonstrate his ARDUINO-based home automation system to see its benefits. With Arduino, you don't need to be a professional "engineer" or "programmer" to play the power of science and technology.
However, simple hardware solutions are not a new concept. The truly differentiation of Arduino is an open source design paradigm. This paradigm is taken by some grassroots movements, or the "tolerant policy" ecosystem, or those suppliers or attachments that ignite global cooperation boom. Even suppliers of MCUs such as MicroshiP and Texas Instruments have begun to note and introduce them to "compatible Arduino" SBCs in their own style.
The IT industry is moving towards the era of "Internet of Things" and bringing the network into the era of hardware and software. A new type of network-based computer and control model has a cloud group in its core zone. In order to be able to succeed in this new era, the company must recognize the hardware, the software also has "Trivergence" between the network. Therefore, we found Microsoft to implement their open source ".NET Gadgeteer" on Maker Faire.
