Download Atmega328P Pinout Arduino Uno Pictures. For those of you who are using an atmega328 with the arduino bootloader code on your own circuit board here is the pinout details which shows the chip pin numbers and the associated arduino pins. Atmega328p is a 28 pin chip as shown in pin diagram above.

Atmel MCU (ATmega328) and the Arduino pin out. | Download ... from www.researchgate.net

Both int0 and int1 are mapped to pins 2 and 3. There are two external interrupt pins on the atmega168/328 called int0 and int1. This core uses the standard arduino uno pinout and will not break compatibility of any existing code or libraries.

In contrast, pin change interrupts can be activated on any of the pins.

The arduino uno has a lot of different pins and therefore we want to go over the different kinds of pins. Both int0 and int1 are mapped to pins 2 and 3. Atmega 328 microcontroller is an eight bit microcontroller based on the risc (reduced instruction set computing) architecture. What's different about this pinout compared to the original one is that.
