EasyBuzz Board is a development tool that features a piezo speaker capable of playing simple sounds.
Sound frequency is between 20Hz and 20kHz. DIP switch is used to configure board connections.
IDC10 connectors are used for easy connection.
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.
Examples provided with this board will show you how to connect the EasyBuzz Board to a microcontroller easily. Each example contains a detailed description of the relevant program including comments. All these examples are written for PIC, dsPIC, AVR and 8051 microcontrollers and can be downloaded from this page as well.
A simple example of using the EasyBuzz board. By pressing the on-board Keypad 4×4 button, the buzzer plays a note by generating a PWM signal of appropriate frequency with 1/2 duty.
By pressing the PORTD command buttons, the buzzer plays a predefined pattern of sound using the Sound library. – pressure on PORTD.0 causes “Test Scales” to play – pressure on PORTD.1 causes “Ode to joy” to play
Board is ideal for adding audio signalization feature to your prototype device.
