See the attachInterrupt() function for details. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
ATMEGA2560 PINOUT SERIAL
Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.Įxternal Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). It comes with more memory space and I/O pins as compared to other boards available in the market. 1.Integrated with the mighty function of the Arduino Mega2560+Ultimaker and Arduino Mega2560+ramps 1. Arduino Mega 2560 is a Microcontroller board based on Atmega2560. Used to receive (RX) and transmit (TX) TTL serial data. What’s more, GT2560 can run over 12V to 24V which gives higher torque and higher rotation rate. In addition, some pins have specialized functions: Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Each of the 54 digital pins on the Arduino 2560 Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.
