When the pin is set LOW or 0, the LED turns OFF. 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. It has 54 digital input/output pins, 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. Arduino Due pinout is explained in detail in this post. This board is powered by a 32-bit ARM cortex-M3 processor Atmel SAM3X8E. Power Indicator: It indicates the status of the battery. The Arduino Mega is a microcontroller board based on the ATmega2560. It was launched by Arduino company in 2012. Receiving Data Indicator LED (Red): When this LED lights up, the board is receiving data from the computer. For details, see the reference and tutorials. DXF Programming The Mega 2560 board can be programmed with the Arduino Software (IDE). Transmitting Data Indicator LED (White): When this LED ON, the Arduino Nano is transmitting data to the computer. OSH: Schematics Arduino Mega 2560 is open-source hardware You can build your own board using the follwing files: EAGLE FILES IN. 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. The Arduino Mega is a microcontroller board based on the ATmega1280 (datasheet). 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. Some problems have occurred, but the problem will be said in a while. The first module is connected to a Mega2560 and the second is connected to Uno. It is used by the microcontrollers to communicate with one or more peripheral devices quickly. Hello Guys, Im trying to make 2 nRF24L01 communicate with each other. SPI stands for Serial Peripheral Interface. SPI pins on the board: D13(SCK), D12(MISO), D11(MOSI)
