Arduino Multi-function Shield is a multifucntional develop board. Arduino is a base with open source platform for the Simple I/o and have used similar to Java C language development environment. Can quick use the Arduino language with Flash or Processing...etc software. Arduino can use developed electronic components such as Switch Sensors or other controller LED a stepper motor or other output device. Arduino can also independent communicate with the software platform for example: flash processing Max/MSP VVVV or other interactive software... Based on the principle of open source Arduino IDE interface allows you to free download to use to develop more amazing interactive work. Features; can match with 2009 UNO LENARDO 2560 major controller seamless docking on the market; 4-channel LED indicators. DS18B20 temperature sensor interface temperature measurement can be done this price not include the DS18B20 if you need you should pay for it. 3296 precision adjustable potentiometer analog input port. Integration of infrared receiving head can be suitable for any infrared remote control experiment this price not include integration of sensor you should pay for it if you need. Four digital tube (driven by 74 hc595 are needed province IO learning SPI) can do the digital tube display experiment (can display temperature voltage count etc.). Three independent key a reset button can do experiments (human machine interface). Buzzer can do experiments. (alarm pronunciation etc.). Bluetooth wireless interface voice module voice recognition module can be used as a wireless communication experiment. Steering gear interface convenient and driver steering gear. Infrared detection interface convenient and infrared docking realize the traffic statistics and so on
