It is programmed in Arduino IDE software like all other boards in terms of coding. Instead it uses ATmega16U2 programmed as a USB-to-serial converter.

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. It can have more memory space as compared to other boards of Arduino. This board is the successor of Arduino MEGA. It is way more powerful than Arduino UNO and also twice as long from it. INTRODUCTION TO Arduino mega 2560Īrduino MEGA 2560 board is just like a brother of Arduino UNO board. We will also highlight some application and projects that are made from this board and much more. You will also get to know about the specifications of this board, pins configuration, components, software that is used to program this board, memory, power requirements and additional shields that can be used with board. After reading this article you will get to know that how this board is different from other boards of Arduino, in which condition or under which specifications we should use this board and why we should prefer this board over others. using the 'mapped pin name' from the pin map diagram, which is 'analog pin 0.In this article we are going to discuss briefly about Arduino Mega 2560 board. Int sensor = 0 // this is the analog pin for the sensor. So I'm not sure how using the mapped pin name can be the right number since I know for a fact that 0 and 1 are usb-serial ports.ĮDIT: Here is the code: //Initialize variables the only problem with that is that the mapped pin name for the analog pin in my example is 0. See my coding example two or three posts up. Ie int pwmPin = 4 // Pwm from *Pin1* of MEga The first line of that table, Digital Pin 4 on your Arduino Mega is pin 1 on the chip itself. You need to use the 'Mapped Pin Name' colunm. The numbers down the left are the physical pins on the chip. That is assuming we are talking about a 168/328 based chip as the mega1280/2560 uses different digital pin numbers to map to it's 16 analog input pins. To make it even more confusing you can utilize analog input pins as digital input or output pins by using the normal digital input and output and mode commands but using arduino digital pin numbers 14 to 19. The 0 is not to be confused with digital pin number 0 which is a different physical pin. Now something about that seems wrong since I heard at one point that 0 and 1 was used for USB-serial connection.įirst you don't use pinMode commands to setup analog input commands, you just use the pin names A0 to A5 in the analogRead(x), where x can be either 0,1,2,3,4,5 or A0, A1.A5. PinMode(sensor, INPUT) // setting it to be an input using the 'mapped pin name' from the pin map diagram, which is 'analog pin 0.' So according to that logic, I would enter this code: //Initialize variables Pin number: 97 pin name: (ADCO)PF0 mapped pin name: Analog Pin 0

For instance, one analog input I would like to use is labeled like this on the pin map diagram: The only place where that doesn't make sense is when I am trying to set some analog pins. That seems fine except for you wouldn't set the int to D49, you would set it to 49.
