Arduino is an open-source, flexible microcontroller system created to aid designers, artists, students, and tinkerers in completing electronic projects. Arduino works by receiving information from sensors and interacting with its environment through lights, motors, and other actuators.
The Arduino Mega 2560 works very much like the Arduino Uno, but adds an additional 40 digital input/output pins, 10 analog inputs and 4 UART hardware serial ports. It can be powered either by USB or a 7-12 VDC. Like the Uno, the Mega 2560 is an excellent device for getting started with Arduino and is compatible with most Shields.
Specifications: • Microcontroller: ATmega2560 • Operating voltage: 5V • Recommended input voltage: 7-12V • Input voltage (limits): 6-20V • Digital I/O pins: 54 (of which 14 provide PWM output) • Analog input pins: 16 • DC current per I/O pin: 40 mA • DC current for 3.3V pin: 50 mA • Flash memory: 256 KB of which 8 KB used by bootloader • SRAM: 8 KB • EPROM: 4 KB • Clock speed: 16 MHz • Dimensions: 4.25" x 2.09".
Note: As Arduino requires learning the Arduino programming language and some degree of electronic knowledge, Parts Express recommends it for experienced and dedicated hobbyists. We suggest thoroughly reading the materials available on the Arduino homepage before proceeding.
