Arduino Mega is an ATmega2560 as core microcontroller development board itself has 54 groups digital I / O input / output terminal (14 groups do PWM outputs), 16 sets of simulation than the input side, group 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the bootloader, download the program directly via USB without having to go through other external writer. Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery.
Rapid growth due to open the original code, as well as the concept of using Java (cross-platform) C language development environment for Arduino peripheral module. The main reason attracted Artist Arduino can quickly use the Arduino language with Flash or Processing ... software communication, to make multimedia interactive works. Arduino development IDE interface is based on open-source principles, allows you to free download for use in project work, school teaching, motor control, interactive works.
Power supply 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 AC-to-DC adapter or the battery can be selected on this control panel. Limit the voltage range of 6V ~~ 12V, but if the voltage supplied is less than 6V, I / O port may not be supplied to a voltage of 5V, and therefore instability; If the voltage is greater than 12V, the regulator device may possibly overheating protection, are more likely to damage the Arduino MEGA. Therefore recommended operating supply 6.5 ~ 12V, the recommended power supply to 7.5V or 9V.
