Keyestudio Mega 2560 R3 board
Introduction
Keyestudio Mega (core to ATmega2560) is a development board (used with16MHz crystal
oscillator ) of microcontroller. There 54 groups of I/O (input/output ) digital ends (of which
14 group to do PWM output), 16 groups of simulation analogy input ends and 4 groups of
UART (hardwareserial ports) in it . Because its bootloader, process can be downloaded directly
with the USB and you don't need to use other external programmer. And its power can be supplied
by the USB, or the AC-to-DC adapter and battery can be also as an external power supply.
Opening source code and using C language developed status in Java concept (cross platform)
make a rapid growth of Arduino peripheral module and application. The main reason to
attract Artist to use Arduino is that they can quickly use all kinds of software communication such
as Arduino language and Flash or Processing and so on. and make multimedia interactive
works. Development interface of Arduino IDE is based on the principle of opening source code,
which you can download freely used in the thematic making, school teaching, television
controlling, interactive works and so on.
Design of Power Supply
There are two choices (direct power supply trough USB or external power supply) for the power
supply system of Arduino Mega, and they can be Automatic switched. External power supply can
be AC-to-DC adapter or battery. Lit rang of voltage of this control board is 6V~12V, but if
