AVR Digital I/O
8. Conclusion
During this tutorial we learned several important digital I/O topics:
- Pin names and locations
- Outputs
- Inputs
- Pin Change Interrupts
- External Interrupts
With these skills, you should be able to do all things digital I/O related. While the digital I/O pins are quite basic and easy to use, they can be used building blocks to design complex interfaces with the outside world.
