Massimo Banzi used to be a teacher in a high technology design school in Ivrea, Italy. He and his students often complained about being unable to get some cheap and user-friendly micro controller. In the winter of 2005, he discussed this problem with David Cuartielles who was a Spanish chip engineer and came to that school as academic visitor. They decided to design their own circuit board and introduced the programming language for circuit board wrote by Banzi’s student, David Mellis. And just after two days, David Mellis worte the program code. And three days later, the circuit board was finished, and it is named Arduino.
Arduino mega is one of models of Arduino. It is an microcontroller development board with ATmega2560 as core. Itself has 54 groups digital I / O input / output terminal (14 groups can do PWM outputs), 16 sets of simulation ratio input side, and 4 groups UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the bootloader, you can download the program directly via USB without having to go through other external writer. You can choose USB to provide power, or use the AC-to-DC adapter and battery as an external power.
Peripheral modules and applications of Arduino have enjoyed rapid growth due to opening to the original code, as well as the use of Java-concept (cross-platform) C language development environment for Arduino . The main reason why Arduino can attracted Artists to use is that it can quickly use the Arduino language with Flash or Processing and other softwares to communicate, to make multimedia interactive works. Arduino has developed IDE interface based on open-source principles, allowing you to free download for use in project work, school teaching, motor control, interactive works. And thats why i recommend you this Arduino compatible R3 Mega2560 ATmega2560-16AU control board with USB cable. As for the power design, there are two options for the power supply system of the Arduino Mega: USB direct power supply or external power supply. The choice of power supply will be switched automatically. External supply can be selected between AC-to-DC adapter and battery. And for safety, it the limit voltage range of t
his board is 6V ~~ 12V, which means if the voltage supplied is less than 6V, I / O port may not be able to supply the voltage to 5V, therefore instability may occur; If the voltage is greater than 12V, the regulator device may start overheating protection, which are more likely to damage the Arduino MEGA. Therefore recommended operating supply range is 6.5 ~ 12V, and the recommended power supply is 7.5V or 9V. The development board have been rigorously tested at the factory before a Blink small program is burned.
Enjoy the creation with this powerful Mega2560 R3 board!
