ARDUINO MEGA 2560 PIN 50 SOFTWARE

Input devices: Ntc thermistor, sensors (like ldr, irled and humidity) and others It can be used by pinMode() for pin direction, analogRead() to read pin status and get digital value for analog signal, care must be taken for internal or external reference voltage selection and Aref pin. Input read signal on Arduino mega boardĪnalog pins: From 0-15(analog) can be used as analog input pin for adc, if not used than it work as normal digital pin.Output low signal on Arduino mega board.Input devices: digital thermistor, push button, ultrasonic sensor, joystick and others Output devices : Relay, LED, buzzer, LCD and others. Digital pins (70): Digital pins (0-53) + Analog (0-15) = Total Digital I/O pins.ĭigital Pins: From 0-53(digital) and 0-15(analog) can be use as input or output for digital transducer and output devices by pinMode() for pin direction, digtalWrite() to write pin and digitalRead() to read pin status. XTAL1,XTAL2: Crystal (16Mhz) is connected to supply clock for controller with 2 bypass capacitor to ground.ĪREF: This pin is used, when we use Adc for analog to digital conversion with external reference voltage for conversion and don’t want to use internal 1.1V or 5v reference. Arduino Mega has inbuilt reset circuit with push button to reset system and this pin can be used by other devices to reset controller. RESET: (Reset input) A low level on this pin for longer than the 4 clock cycle will generate a reset.

USB (Programming with ATmega 8), ICSP (programming), SPI, I2C and USARTĪrduino Mega – Advanced Features Arduino MegaĪrduino Mega 2560 is also packed with additional features like Analog Comparator, External Interrupt & Software Interrupt, Power Saving Mode, Inbuilt Temperature Sensor, RTC and more. Arduino Mega 2560 SpecificationsĪrduino Mega – Basic Features Arduino Mega Due to the many numbers of pins, it is not usually used for common projects but you can find them in much more complex ones like Radon detectors, 3D printers, temperature sensing, IOT applications, real-time data monitoring applications etc. The Arduino Mega 2560 is a replacement of the old Arduino Mega, and so in general reference, it will be called without the ‘2560’ extension. It supports ICSP as well as USB microcontroller programming with PC. It is also compatible with the different type of boards like high-level signal (5V) or low-level signal (3.3V) with I/O ref pin.īrownout and watchdog help to make the system more reliable and robust. With large FLASH memory and SRAM, this board can handle large system program with ease. Other features include JTAG support for programming, debugging and troubleshooting. It has more than 5 pins for Vcc and Gnd to connect other devices to Arduino Mega.

Secondly, it has inbuilt RTC and other features like analog comparator, advanced timer, interrupt for controller wakeup mechanism to save more power and fast speed with 16 Mhz crystal clock to get 16 MIBS.

First feature is the large I/O system design with inbuilt 16 analog transducers and 54 digital transducers that supports with USART and other communication modes.

When cheaper boards are available, why go with Arduino Mega? The main reason behind this is the additional features that are inbuilt with this board.
