This board comes with 54 pins and 16 analog pins with more memory to store the code. This is where Arduino Mega 2560 comes in handy. However, when the project goes complex, a board with less memory fails to complete the task. Here's the video presentation of Arduino Mega 2560:Īll the boards mentioned above work perfectly for a number of Arduino Projects when you require a simple task to be completed with fewer I/O pins and memory. Just plug and play with the board as per your requirement. Everything is already built in the board that makes this device readily available. In terms of coding, all these boards are programmed in Arduino IDE software and you don't need to attach extra components or devices to put them in running condition. There are some basic features like PCB layout design, size, number of analog pins and breadboard friendly nature that make them different from each other. All these boards function similarly in one way or the other. I have updated articles previously on Arduino Uno, Arduino Nano, and Arduino Pro Mini. Arduino Boards have revitalized the automation industry with their easy-to-use platform where everyone with little or no technical background can get started with learning some basic skills to program and run the board. It is a microcontroller board based on Atmega 2560 microcontroller. Today, I am going to unlock the details on the Introduction to Arduino Mega 2560. When the pin is set LOW or 0, the LED turns OFF.Hey Fellas! Hope you are doing well. When this pin is set HIGH or 1, the LED turns ON. Pin 13 LED Indicator (Blue): In the board, there is a built-in LED connected to digital pin 13. It can also display the voltage of the battery onto the LCD connected to the Arduino board. Power Indicator: It indicates the status of the battery. Receiving Data Indicator LED (Red): When this LED lights up, the board is receiving data from the computer. Transmitting Data Indicator LED (White): When this LED ON, the Arduino Nano is transmitting data to the computer. LED Indicators on Arduino Nano:Īrduino Nano board consist of 4 LED indicators: Sending a signal to this pin does nothing. It provides the voltage reference at which the microcontroller is currently operating. REF: This pin is the input/output reference. If this pin is supplied with 5 V, the board will reset automatically GND (Ground pins): There is a total of 5 ground pins on the board. UART pins on board: D0(TX), D1(RX) Other pins: It also represents the successful flow of data from the computer to the board. The TXD is used for transmitting the data, and RXD is used for receiving the data during serial communication. UART Pins: TXD and RXD pins are used for serial communication. This allows us to have multiple SPI peripheral devices sharing the same MISO, MOSI, and CLK lines.Įxternal Interrupts (2 and 3)- These pins can be used to trigger an external interrupt in the following conditions: a low value, a rising or falling edge, or a change in value. When its value HIGH, it ignores the master. When a device’s Slave Select pin value is LOW, it can communicate with the master. This line is used for sending data to the peripherals. MOSI-It stands for Master Output/ Slave Input.This data line in the MISO pin is used to receive the data from the Slave. MISO-It stands for Master Input/ Slave Output.These are the clock pulses, that are used to synchronize the transfer of data. It is used by the microcontrollers to communicate with one or more peripheral devices quickly. SPI stands for Serial Peripheral Interface. SPI pins on the board: D13(SCK), D12(MISO), D11(MOSI)
