This pin is used for serial UART communication with pc or other serial devices for purpose of data sharing and logging. It enables the Arduino to communicate with serial devices.

UART stands for Universal Asynchronous Receiver and Transmitter. This allows us to have multiple SPI peripheral devices sharing the same MISO, MOSI, and CLK lines Which pins are UART ? When it’s 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 send the data to the master.

MISO-It stands for Master Input/ Slave Output.

These are the clock pulses, that are used to synchronize the transfer of data. There are three common lines to all the peripheral devices: 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.

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. Voltage Regulator-The voltage regulator converts the input voltage to 5V.
