Arduino is an open-source physical computing stage dependent on a straightforward I/o board and an improved environment that actualizes the Processing/Wiring dialect. Arduino can be utilized to create remain solitary intelligent items or can be associated with programming on your PC (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for nothing (as of now for Mac OS X, Windows, and Linux).
The Arduino Mega is a microcontroller board dependent on theATmega2560. It has 54 computerized input/yield pins (of which 14 can be utilized as PWM yields), 16 simple information sources, 4UARTs (equipment sequential ports), a 16 MHz gem oscillator, a USB association, a power jack, an ICSP header, and a reset catch. It contains everything expected to help the microcontroller; just interface it to a PC with a USB link or power it with an AC-to-DC connector or battery to begin. The Mega is perfect with most shields intended for the Arduino Duemilanove or Diecimila.
The Mega 2560 R3 likewise includes SDA and SCL sticks beside the AREF. What's more, there are two new sticks put close to the RESET stick. One is the IOREF that enable the shields to adjust to the voltage gave from the board. The other is a not associated and is held for future purposes. The Mega 2560 R3 works with every current shield, however, can adjust to new shields which utilize these extra sticks.
