MotoGP 2 is surprisingly sim-like in both design and execution.
More to the point, the game does a bang-up job of communicating the unique, intense physics at play in keeping a 180-mph GP bike on the straight and narrow. Though no one is likely to confuse it with the much-heralded Superbike series, it still delivers first-rate racing, complete with 20 licensed riders and all 16 tracks from the 2002 GP circuit. MotoGP 2 allows you to execute wheelies, endos, and powerslides with some judicious throttle, brake, and rider manipulation.There are some weaknesses, to be sure — this is an arcade racer, after all — including a highly unrealistic off-course slowdown penalty (where putting a wheel wrong is tantamount to dynamiting the brakes) as well as an absence of proper brake lockups.With a number of racing modes to choose from, including Quick Race, Career, Stunt, and Time Trial, variable racing experiences are easy to find.

INTRODUCTION TO Arduino mega 2560
Arduino MEGA 2560 board is just like a brother of Arduino UNO board. It is way more powerful than Arduino UNO and also twice as long from it. This board is the successor of Arduino MEGA. It can be named as ATMega2560. It can have more memory space as compared to other boards of Arduino. Arduino MEGA 2560 is different from all other boards of Arduino that came before as they don’t use the FTDI USB-to-serial driver chip. Instead it uses ATmega16U2 programmed as a USB-to-serial converter. It is programmed in Arduino IDE software like all other boards in terms of coding. We don’t need to attach extra components or devices to make this board in running condition to use. As per our requirements we can just plug and play with this board as everything is built in that makes it readily available.
Arduino Mega 2560 is an amazing microcontroller board for the projects that need large amount of input output pins or if high processing power is required. It is designed for more complex projects because as for simple projects large amount of input output pins are useless and a board with less memory fails to achieve our requirements. It can be used as a stand-alone project or in combination with other boards. Mostly it is used for creating a stand-alone project

POWER SUPPLY for Arduino mega 2560
In order to use this board efficiently and without getting the board burnt / damaged we should be cautious in selecting a power source for our microcontroller board as for any electro mechanical device to work , selecting a power source is a crucial step.
Arduino Mega 2560 can have power supply of two voltages i.e. 3.3 V and 5 V
- 3 voltage supply can be generated with the help of on board regulator and the maximum current is 50 mA that can pass through it.
- 5 volt supply can also be generated and regulated on board. DC supply can be given via power jack or by using USB cable port
- Vin is an input power that can be used within the external power in range.
- GND is a ground terminal which can be connected to the ground of connection from which power is going to be supplied.
In short there are 3 ways to power our board. We can use either USB cable to power our board and then transfer our code to board or we can power it up by Vin of board or via power jack. These last two methods to provide power to the board can be used once you built and compile code into board via USB cable.
Software for programming for Arduino mega 2560
- Just like other Arduino boards , Arduino MEGA 2560 also uses Arduino IDE. This IDE supports C programming so we have to write program in C language. We can type our program in it and then burn that code in our microcontroller and we can also change our code according to requirements. The code that we make on software is known as sketch and it is burned in software and then transferred to our microcontroller using USB cable.
- To reset the board and to erase all previous data from microcontroller we can use the reset button on board
- Arduino Mega 2560 comes with built-in boot loader and it rules out the usage of external burner for burning code into the microcontroller. This boot loader uses STK500 protocol for communication purposes.
- After compiling and burning program / sketch on board , we can unplug USB cable and it eventually removes power from board. If we have to incorporate this board in our project then we can power it by using power jack or Vin pin of our board
- Another feature that is included in Arduino mega 2560 is multitasking. Although IDE doesn’t support this feature but different operating system can be used to make C program for this purpose and doing so also provides flexibility to use our own build program using ISP connector of board.
Shield Compatibility of Arduino mega 2560
The first and foremost thing that we should keep in our mind before using any shield is to make assured of its operating voltage. We have to make definite that the operating voltage of that shield is compatible with our board voltage as shields with higher operating voltage i.e. above 3.3 V or 5 V can damage our board. However mostly boards are having operating voltage of 3.3 V or 5 V but we should be careful in selection of shields which we are going to use with our microcontroller board to prevent our board from damage. Wedding cake design games. The second most important thing that we should make sure is that the header distribution of the shield we are going to use should resonate with pin distribution of our board so that we can simply attach the shield with our board to make it ready to use. Arduino mega 2560 is compatible with many shields that are designed for some other version of Arduino board. Some of the shields and their purpose for which they are used are listed below.
- Motor Controller Shield : the most used and stocked shield is this shield because it make possible for our microcontroller Arduino mega 2560 to run many motors and here our many input output pins comes handy to make all motors run at once
- Arduino Mega Wi-Fi Shield: If you want to work on making your project wireless then it’s the most practical shield you will ever find. It’s great shield for making our robot work wirelessly.
- DF Robot Multi Pin Shield : In this shield we have space for 3 wireless add on.
- Arduino Prototyping Shield : To make prototype of our project.
APPLICATIONS of Arduino mega 2560
As discussed earlier, usage of Arduino mega board is pretty uncommon because of large number of input output pins. But it’s great for some projects like
- 8 bit computer
- 3D printer
- To control and handle more than one motor
- Robot with many sensors
- CNC router
- Temperature detection and sensation
- Detection of water level
- Automation and security projects
- Internet of things applications
- Multitasking or parallel programming

$begingroup$Arduino Mega Using Serial Software Pdf
I'm trying to figure out if I can send and receive serial data on ports 23 and 25 of the Arduino Mega 2560, and I'm very confused by seemingly contradictory information on the Arduino website.From the SoftwareSerial page:
Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
On the Arduino Mega page:
A SoftwareSerial library allows for serial communication on any of the Mega2560's digital pins.
In general there is a master device that controls all communications over these links and slave devices that just do what they're told.When we talk about Ethernet, we're talking about networking. Parallel and serial connections. One computer talks to one printer or one modem (per cable). Multiple computers are connected a network, and none of them is necessarily master or slave.
The pins it specifies as compatible with interrupts are:
2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2).
![Arduino nano software serial Arduino nano software serial](/uploads/1/2/5/2/125297153/765223553.jpg)
and have no overlap with the pins that the first quote. These seem completely contradictory. Am I missing something? Can I use serial on ports 23 and 25?

$begingroup$The reason behind the discrepancy in documentation is that the documentation refers to two different versions of the software and it is out of date.
In Arduino version 0023 and below, SoftSerial was a very basic library written by David Mellis. It just uses millis(), digitalRead/Write and blocks when sending or receiving. This means it can work on any pin. However, it works badly and slowly. I would strongly recommend avoiding this.
In Arduino version 1 and above, SoftSerial was replaced with NewSoftSerial. This uses interrupts and timers, and is far more efficient. This limits the pins that it can work on though to ones that have pin change interrupts.
With respect to the contradictory pins; there are two types of interrupt pin on the ATmega2560 - external interrupts (INT7 - INT0) and pin change interrupts (PCINT23 - PCINT0). External interrupts are more complex and can be configured to trigger on rising and/or falling edges. Pin change interrupts trigger as long as any change occurs.
The long list of:
are pin change interrupts which are what are required for NewSoftSerial (called SoftSerial in Arduino 1.0 and above).
The short list of:
Arduino Mega Using Serial Software Windows 10
are external interrupts.
Arduino Mega Using Serial Software List
You can see these on the pin mapping diagram for the ATmega2560 (which is correct, AFAIK). Function of the interrupt pins is described on page 105 onwards of the datasheet.
There are 4 hardware USARTs on the ATmega2560. These are far easier to use and far more efficient than any software serial library. They are on pins 0/1, 14/15, 16/17, 18/19.
There is also AltSoftSerial which is better than NewSoftSerial in terms of performance, but is even more limited in pin choice.
At this stage, I have to ask 'why those pins?'. Could the design not change?

$endgroup$$begingroup$You stumbled upon the difference between hardware serial / UART and serial emulated in software.
hardware serial
The following pins support hardware serial / UART. It implies little processor overhead as the hardware takes care of the tough work.
Serial: 0 (RX) and 1 (TX); Serial 1: 19 (RX) and 18 (TX); Serial 2: 17 (RX) and 16 (TX); Serial 3: 15 (RX) and 14 (TX). Used to receive (RX) and transmit (TX) TTL serial data. Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.
Use the commands as found on this page: http://arduino.cc/en/Reference/Serial
software serial
The SoftwareSerial library you refer to does not use the integrated UART hardware, instead it uses software to emulate the serial port. It uses various timing mechanisms (like interrupts) and bit banging (directly driving pins low/high) to act as if it were a real UART.
Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
Use the commands as found on this page: http://www.arduino.cc/en/Reference/SoftwareSerial
in conclusion
Without knowing your exact requirements, I'd say first use the hardware UART's (because of lower CPU overhead) and if you run out of those, use SoftwareSerial.
