Voltage Regulator-The voltage regulator converts the input voltage to 5V . The primary use of a voltage regulator is to control the voltage level in the Arduino board. Even if there are any changes in the input voltage of the regulator, the output voltage is constant and steady. If you are looking at upgrading from previous Arduino designs, or if you are just interested in boards with similar functionality, at Arduino you can find: You'll need to select the entry in the Tools > Board menu that corresponds to your Arduino board. You have a Mega2560, therefore it has an ATmega2560 microcontroller, selected by default as processor.

Those boards work fine unless you're doing something wierd that requires reprogramming the 16u2 to make it appear as some other USB device. An Arduino mega board includes a boot loader which eliminates an external burner utilization to burn the program code into the Arduino board. Here, the communication of the boot loader can be done using an STK500 protocol. The Mega 2560 Pro is compatible with the Arduino MEGA 2560 with a reduced physical size for embedded applications. Following in the MEGA 2560 architecture, the Pro provides a large amount of I/O and memory, making it ideal for larger projects. It is built on the Atmel ATmega2560 with a CH340G USB-UART interface chip. |You are free to do anything you want with this code. There is no license. You are allowed to use/copy/change/share the code without having to attribute myself, You can find in the Getting Started with Arduino MEGA2560 Rev 3 section all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.The optional component kit includes all the parts needed to completely populate the core portion of the board. These are the parts we provide, but similar value parts out of your parts bin can also be used. Six/Twelve PWM Channels with Programmable Resolution from 2 to 16 Bits (ATmega1281/2561, ATmega640/1280/2560) These pins accept inputs in the form of Analog signals and return values that range between 0 and 1023 (that’s because the Arduino Mega has a 10-bit Analog to Digital converter or 2 10 resolution). This quality board is part of our custom Pro Series boards and is specifically designed to mount the Mega 2560 Pro module. The board provides flexible options for input power and power distribution including a built-in DC-DC converter module. Available as board only or with an optional component kit to build the base system and mount the Mega 2560 Pro MCU module.

Nowadays we use USB to connect devices to our computers. The ATmega2560 is a very nice microcontroller but it doesn't have any USB capabilities. For this reason a separate chip is usually added to Arduino boards that acts as a bridge between the serial communication of the ATmega2560 and the USB of your computer. The computer then creates a virtual COM port that makes it seem like your board is connected to a serial port on your computer even though it's connected via USB. The ATmega16U2 is a microcontroller that has native USB capabilities so it can be programmed to act as a serial-USB bridge. The board can also be powered by applying 5V to the 5V pins. This bypasses the on-board regulators and and should only be used if a stable 5V power source is available. This pin is used for serial UART communication with pc or other serial devices for purpose of data sharing and logging. It is used with serial.Begin() function to set baud rate setting and start communication with serial.Println() function to print an array of char on another device output. The Mega 2560 has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed. Power

The TCCRnB is a 8 bit number. The first three bits (from right to left!) are called CS02, CS01, CS00, and they are the bits we have to change.The Mega 2560 can be powered via the USB connection or with an external power supply. The power source is selected automatically.
