![]() ![]() They are used by the microcontrollers to communicate with one or more peripheral devices quickly. The PINs 50, 51, 52, and 53 are used as SPI pins. It stands for Serial Peripheral Interface. That’s why it is called a data line, while SCL is called a clock line. It is defined as the line used by the slave and master to send and receive data. The Serial Clock is generated by the master device. It is used to synchronize the shift of data between the two devices. It is defined as the line that transfers the clock data. The I2C uses two lines to send and receive data: a serial clock pin uses (SCL) and a serial data (SDA) (SDA) pin. It is the two-wire serial communication protocol. The Vcc voltage value can be negative or positive to the GND pin. It is also called the primary voltage for ICs present on the Arduino board. V in–It is the modulated DC supply voltage, which is used to regulate the ICs used in the connection. The program is uploaded to the board serially from the computer through the USB cable. ![]() This port can be used to power the device from the 5V supply and allows us to connect the board to the computer. USB B-port- The USB Interface is used to plug in the USB cable. Note: Above 12 volts, the board may overheat and voltage below 7 volts might not be sufficient to power the board. ![]() The board can be powered by an adapter that ranges between 5-20 volts but the manufacturer recommends keeping it between 7-12 volts. The barrel jack is usually connected to an adapter. There are three ways to power the Arduino Mega Board:īarrel Jack – The Barrel jack, or 7-12V DC Power Jack can be used to power our Arduino board. Are you a beginner? Can't decide which book to read? Check out this article on Best Arduino Books for beginners How to power the Arduino Mega 2560? RESET Button-It is used to Reset the board, recommended to press it each time we flash some code to the board. It provides the basic timing and control to the board. This allows it to effectively find a balance between power consumption and processing speed.Ĭrystal Oscillator- The Crystal oscillator has a frequency of 16MHz, which provides the clock signal to the microcontroller. Even if there are any changes in the input voltage of the regulator, the output voltage is constant and steady.ĪTmega2560P : It is an 8-bit AVR RISC (Reduced Instruction Set Computer) based microcontroller that executes powerful instructions in a single clock cycle. The primary use of a voltage regulator is to control the voltage level in the Arduino board. XTAL1,XTAL2: The crystal oscillator (16Mhz) is connected to the controller clock and is grounded through 2 bypass capacitors.ĪREF: Using this pin, when we use ADC for analog-to-digital conversion, use external reference voltage for conversion instead of reference voltage from internal 1.1V or 5v reference.Voltage Regulator-The voltage regulator converts the input voltage to 5V. The Arduino Mega has a built-in reset circuit, a key reset system, and can be used as a reset controller for other devices. RESET: (Reset input) The low level of this pin exceeds 4 clock cycles and the board will reset. The Arduino Mega 2560 also adds features such as analog comparators, external and software interrupts, power save mode, built-in temperature sensor, RTC, and more. USB (Programming with ATmega 8), ICSP (programming), SPI, I2C and USART Arduino Mega 2560 Hardware Specifications Arduino Mega 2560 So for some more complex projects, this is an excellent choice. The Arduino Mega 2560 is a replacement for the older model Arduino Mega, so, it will be named the "2560" extension. Other features of the Arduino Mega 2560 include JTAG support for programming, debugging and troubleshooting large flash and SRAM that can easily handle bulky programs it is also compatible with different types of modules such as high-level (5V) or low-voltage Flat (3.3V) and I/O ref pins it supports ICSP and USB microcontroller programming on the PC side. There are more than 5 sets of Vcc and Gnd pins, which can easily connect other devices to the Arduino Mega 2560. Built-in RTC and other functions, such as analog comparator, advanced timer, controller wake-up mechanism interrupt, etc., 16MHz crystal clock can get 16 MIBS, and it saves power and is fast. For example: it has built-in 16 analog sensors and 54 digital sensor interfaces, and supports USART and other communication modes. Arduino Mega 2560 has many features that other boards do not have. Why choose Arduino Mega? The main reason is that this board is more convenient for expansion. There are cheaper Arduino boards on the market. ![]()
