| + | After blinking the leds and Controlling tnem with switches, its time to make some noise using the buzzer. In the first part of the tutorial, we will beep the buzzer every 2secs. At the end we will control the buzzer using a switch. |

| − | ==Type 2:Using Explore Ultra AVR Dev Kit==
| + | |
| − | ===Components Used===
| + | |
| − | 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.
