The Explore Ultra AVR Kit comes with all the things required, not just for this experiment but for the entire series. And even if you think of migrating to PIC or Arduino, you'll have breakout boards that fit on to this, hence we believe it is a great investment for learning hands on Embedded Systems. The kit is fully open source, you may use the schematics, the design files and all of the source code and build something cool on your own. And when you do that do not forget to share with us what you've done. We would be happy to see you building something cool. | The Explore Ultra AVR Kit comes with all the things required, not just for this experiment but for the entire series.

Objective
After blinking the leds, its time control these leds depending on external inputs. In this tutorial we will interface a DIP switch to one of the Port's and display its status on LED's connected to other port.
Register Configuration
Please refer the below tutorial for basics of GPIO register configuration.
Code
Below points needs to be considered for this example.
- Include the io.h file as it has the definitions for all the PORT registers.
- Include delay.h file to use the delay functions.
- Configure the PORT as Output before writing any data to PORT pins.

Explore Ultra AVR Dev Kit
The Explore Ultra AVR Kit comes with all the things required, not just for this experiment but for the entire series. And even if you think of migrating to PIC or Arduino, you'll have breakout boards that fit on to this, hence we believe it is a great investment for learning hands on Embedded Systems. The kit is fully open source, you may use the schematics, the design files and all of the source code and build something cool on your own. And when you do that do not forget to share with us what you've done. We would be happy to see you building something cool.
- Explore Ultra AVR Dev Kit: Buy from EE Store
