The programming of an Arduino Mega 2560 can be done with the help of an IDE (Arduino Software), and it supports C-programming language. Here the sketch is the code in the software which is burned within the software and then moved to the Arduino board using a USB cable. There are a couple of very similar boards I've seen around, most are based in CH340G serial adapters (more durable/reliable that the 16u2 used on official boards, but without the special features of that which hardly anyone uses). Robotdyn is one if the better chinese elecronic crap companies.

The Mega Pro Mini functionalities are identical tothe Arduino Mega 2560. Even though itisanEmbed board, itissolid stable asthe Mega Board. Ituses the original chip, and a16MHz high-quality quartz resonators ispresent onthe board. The Mega Pro Embed CH340G / ATmega2560 board is based on the ATmega2560 microcontroller and the USB-UART adapter CH340. The board is compatible with Mega 2560 (Arduino-Compatible) The board has acompact form factor of38X55mm and isanexcellent solution for developing projects based onATmega2560. As you can see, a given timer controls more than one pin (every change about a timer will affect all pins depending on it!).The distributed adjacent power and ground runs allow for easy placement of additional bypass or filter caps as needed if the board is used to mount high speed / high current circuits.

The 5V output of the on-board MCU regulator is brought out to the V Rail and S Rail power selection jumpers and is labeled 5V on the board. int cpsCount = 0; // Used for calculating CPM. This var counts the amount of interrupt events in one second. You can power the board or power the pins through the MicroUSB connector. The voltage regulator (LDO) can handle input voltages from 6V to 9V (peak 18V) DC. The voltage regulator allows to use up to 18V as an input value, however, we do not recommend exceeding the recommended values aforementioned, since this can lead to excessive heat and damage the device. This Arduino board includes a LED and that is allied to pin-13 which is named as digital pin 13. This LED can be operated based on the high and low values of the pin. This will give you to modify the programming skills in real time.Built-in DC-DC converter module to power separate power rail for servo motors or can power entire power rail static uint32_t radmonInterval = 30000; // How often to submit to Radmon.org (60000ms = 60 seconds.) Please don't set this to less than 60000 as recommended minimum submission time for Radmon.org is 60 seconds. The USB connection with the PC is necessary to program the board and not just to power it up. The Mega2560 automatically draw power from either the USB or an external power supply. Connect the board to your computer using the USB cable. The green power LED (labelled PWR) should go on. Open your first sketch
