#ARDUINO MEGA PROJECTS SERIAL#
The serial pins of this board have four combinations. Tx indicates the transmission of information whereas the RX indicates receive data. The serial pins of this board like TXD and RXD are used to transmit & receive the serial data. However, the output voltage through this pin to the board will be automatically set up to 5V. The voltage provided by the power jack can be accessed through this pin. The range of supplied input voltage to the board ranges from 7volts to 20volts. The Arduino mega board includes 5-GND pins where one of these pins can be used whenever the project requires. The max power can be drawn by this is 50mA. It can be attained from Vin-pin of the board or one more regulated voltage supply-5V otherwise USB cable, whereas another voltage regulation can be offered by 3.3V0-pin.
This RPS (regulated power supply) provides the power to the microcontroller as well as other components which are used over the Arduino mega board. These pins are used for providing o/p regulated voltage approximately 5V.
When we compare with other types of Arduino boards, these boards are physically superior. These boards offer flexible work memory space is the more & processing power that permits to work with different types of sensors without delay. By using this board, the Arduino mega projected can be designed. All analog pins of this board can be used as digital I/O pins. Every pin of this board comes by a particular function which is allied with it. The pin configuration of this Arduino mega 2560 board is shown below. The USB host chip used in this is MAX3421E.The electrically erasable programmable read-only memory (EEPROM) is 4 KB.The static random access memory (SRAM) is 8 KB.Flash Memory like 256 KB where 8 KB of flash memory is used with the help of bootloader.DC Current for each input/output pin is 40 mA.The digital input/output pins are 54 where 15 of these pins will supply PWM o/p.The input voltage will range from 6volts to 20volts.The recommended Input Voltage will range from 7volts to 12volts.The operating voltage of this microcontroller is 5volts.The specifications of Arduino Mega include the following. These boards work with every existing shield although can adjust to latest shields which utilize these extra pins.
Another pin is not associated & it is kept for upcoming purposes. One pin is the IOREF that permit the shields to adjust the voltage offered from the Arduino board. Additionally, there are two latest pins located near the RST pin. The SCL & SDA pins of Mega 2560 R3 board connects to beside the AREF pin. This board can be protected from the unexpected electrical discharge by placing a base plate.
#ARDUINO MEGA PROJECTS PC#
So, the power supply of this board can be done by connecting it to a PC using a USB cable, or battery or an AC-DC adapter. This board mainly includes everything which is essential for supporting the microcontroller. It includes digital input/output pins-54, where 16 pins are analog inputs, 14 are used like PWM outputs hardware serial ports ( UARTs) – 4, a crystal oscillator-16 MHz, an ICSP header, a power jack, a USB connection, as well as an RST button. In the next section, I will discuss the specific data structure used by the card/tag to store information that we can either read or write to.The microcontroller board like “Arduino Mega” depends on the ATmega2560 microcontroller. The reader's antenna (in our case, the antenna on the RC522 is the embedded coil-like structure on the face) which will send out radio waves, which in turn will energize a coil in the card/tag (within close proximity) and that converted electricity will be used by the transponder (device which receives and emits radio frequency signals) within the card to send back the information stored within it in the form of more radio waves. The working principle of RFID communication is fairly straightforward. The card, on the other hand, contains a chip which can store information and allow us to alter it by writing to one of its many blocks, which I will go into more detail in the next section as it falls under the RFID's data structure. In the reader, there is a Radio Frequency module and an antenna which generates an electromagnetic field.
