After blinking the leds and Controlling them using switches, its time to make some noise using the buzzer. In the first part of the tutorial, we will beep the buzzer with a delay of 1sec. At the end we will control the buzzer using a switch.
Contents
Register Configuration
Please refer the below tutorial for basics of GPIO register configuration.
Buzzer Beep 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.
- Turn ON and OFF the buzzer with a delay of 1sec.
Switch And Buzzer 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.
- Configure PORTA as inputs to read the switch status.
- Configure the PORTC as Output to turn ON/OFF the Buzzer.
- Continuously read the switch status and control the buzzer accordingly.

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.
