Figure 1: EasyBuzz additional board
How to connect the board?
The EasyBuzz additional board can be easily connected to a development system via a 2x5 connector CN1 on the
additional board.
How to use the board?
In order to enable the EasyBuzz board to emit audio signals, it is necessary to connect it to a development system
and write the appropriate program to be loaded into the microcontroller. The program should dene which of the
microcontroller pins will be used to generate a voltage signal of specic frequency. Resonant frequency is 3.8kHz,
whereas frequencies in a range between 20Hz and 20kHz may also be used. The best sound quality is achieved when
using frequencies between 2 and 4kHz.
In order to connect the board to the microcontoller on the development system, it is necessary to set the appropriate
switch on DIP switch SW1 to the ON position. It depends on the microcontroller pin, used to emit voltage signal, which
one of these switches will be set ON.
EasyBuzz
The EasyBuzz additional board is used to emit audio signals by using a piezo buzzer supplied on the board.
Key features:
- 3.8kHz resonant frequency;
- Low power consumption;
- 3.3 or 5V DC power supply voltage.
