![]() ![]() This pin is used to program the firmware of the arduino board. ICSP stands for In-Circuit Serial Programming. These external interrupt pins can be used to trigger an interrupt on a low value, a rising or falling edge, or a change in value. It uses two lines for sending and receiving data which are:-Įxternal interrupts of arduino mega can be formed by using 6 pins which are :. I2C is a two-wire serial communication protocol. Board Arduino Mega 2560 adalah sebuah Board Arduino yang menggunakan ic Mikrokontroler ATmega 2560.Board ini memiliki Pin I/O yang relatif banyak, 54 digital Input / Output,15 buah di antaranya dapat di gunakan sebagai output PWM, 16 buah analog Input, 4 UART. It stands for inter – integrated circuits. ARDUINO MEGA 2560 MIKROKONTROLER ATmega2560. When it’s value is HIGH, it ignores the master. When a device’s Slave Select pin value is LOW, it can communicate with the master. It is used by the master device to select the slave with which it wants to establish the connection. It also have one unique line used by master which is:. This line is used for sending data to the peripherals or slaves. 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.Note that it does not match the Arduino Mega pin mapping for the standard Arduino pins. The 'AVR pinout' pin mapping is shown in this diagram: 4500×3600 1020 KB. These are the clock pulses that are used to synchronize the transfer of data. This is only done for the 'AVR pinout' so after installing MegaCore you need to select Tools > Board > ATmega2560, then Tools > Pinout > AVR pinout. ![]() 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.There are 3 common lines to all the peripheral devices which are:. 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. Because of its brawnier processor, the Mega has 54 digital I/O pins (15 of which can provide PWM output) and 16 analog pins, which is almost four times that of its little brother, the Uno. 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. ![]()
