EASY BUZZ BOARD

The EasyBuzz Board features a Piezo Speaker capable of emitting audio signals. For the piezo buzzer to operate normally it is necessary to generate a voltage signal of specified frequency. The voltage signal is generated in the microcontroller by the appropriate code written to its memory. Remember, when writing the voltage signal generation code, the piezo buzzer’s resonant frequency is 3.8kHz. Other frequencies in the range between 20Hz and 20kHz can also be used, but the best performance is provided by frequencies ranging between 2kHz and 4kHz. The voltage signal can be generated via microcontroller pins, whereas DIP switch is used to select which of these two pins is to be used.
