The Arduino Mega is a microcontroller board based on the The Arduino Mega can be powered via the USB connection or with an external power supply. High Performance, Low Power Atmel® AVR® 8-Bit Microcontroller .. The ATmega//// AVR is supported with a full suite. The Arduino Mega is a microcontroller board based on the ATmega ( datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM.

It contains everything needed to support the 26500 simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.
Arduino Mega atjega open-source hardware! You can build your own board using the follwing files: The ATmega16U2 or 8U2 in the rev1 and rev2 boards firmware source code is available in the Arduino repository.
The Mega 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 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.
The Mega can be atemga via the USB connection or with an external power supply. The power source is selected automatically.

The adapter can be connected by plugging a 2. The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may become unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts. They operate at 5 volts.
Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor disconnected by default of k ohm. A maximum of 40mA is the value that must not be exceeded to avoid permanent damage to the microcontroller. The Mega has 16 analog inputs, each of which provide 10 bits of resolution i. There are a couple of other pins on the board:. The Mega board has a number of facilities for communicating with a computer, another board, or other microcontrollers.
An ATmega16U2 ATmega 8U2 on the revision 1 and revision 2 boards on the board channels one of these over USB and provides a virtual com port to software on the computer Windows machines will need a.
The Arduino Software IDE includes a serial monitor which allows simple textual data to be sent to and from the board.

The maximum length and width of the Mega PCB are 4 and 2. Three screw holes allow the board to be attached to a surface atmmega case.
Note that the distance between digital pins 7 and 8 is mil 0. The Mega is designed to be compatible with most shields designed for the Uno and the older Diecimila or Duemilanove Arduino boards. Furthermore, the main UART serial port is located on the same pins attmega and 1as are external interrupts 0 and 1 pins 2 and 3 respectively.
Rather then requiring a physical press of the reset button before an upload, the Mega is designed in a way that allows 6250 to be reset by software running on a connected computer. When this line is asserted taken lowthe reset line drops long enough to reset the chip. The Arduino Software IDE uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment.
This means that the bootloader can have a shorter timeout, as the lowering of DTR atmegx be well-coordinated with the start of the upload.
This setup has other implications. For the following half-second or so, the bootloader is running on the ATMega While it is programmed at,ega ignore malformed data i. If a sketch running on the board receives one-time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.
The Mega board contains a trace that can be cut to disable the auto-reset. 2605 pads qtmega either side of the trace can be soldered together amtega re-enable it. Revision 3 of the Arduino board and the current Genuino Mega have the following improved features:. Project tutorial by TheTNR. Originally designed inthis is the revival of Helios.
