2. Soldering the headers Before using your click board, make sure to solder the provided 1x8 male headers to both sides of the board. Two 1x8 male headers are included with the board in the package. 1 BUZZ click 2 3 1. Introduction 4. Creating Sound On-board buzzer driver can be connected to either digital (GPI) or PWM line. You can create sound using Sound library supported in mikroElektronika compilers, or utilize Turn the board upside down, so that Turn the board upward again. Make sure microcontroller internal PWM module to bottom side is facing you upwards. Place to align the headers so that they are create the signal for the buzzer. Signal shorter parts of the header pins in the perpendicular to the board, then solder the frequency determines the sound pitch, and Front and back side appearance both soldering pad locations. pins carefully. the duty cycle determines the amplitude of the BUZZ click Board (sound volume). BUZZ Click is an accessory board in mikroBus form factor. Board features 3. Plugging the board in a piezo speaker capable of emitting audio click signals. Buzzers resonant frequency is 3.8kHz Once you have soldered the headers your (where you can expect its best performance). board is ready to be placed into desired BOARD On-board buzzer driver can be connected mikroBUS socket. Make sure to align the www.mikroe.com to either digital (GPI) or PWM line. You can cut in the lower-right part of the board use either of those two pins to provide the with the markings on the silkscreen at the BUZZ click Manual signal from the microcontroller to the buzzer mikroBUS socket. If all the pins are aligned ver. 1.00 driver. Board is set to use 5V power supply by correctly, push the board all the way default. Solder PWR SEL SMD jumper to 3.3V into the socket. position if used with 3.3V systems. 0 100000 0200436. Power supply selection 5. Buzz click Board Schematics On-board PWR SEL zero- ohm resistor (SMD jumper) is used to determine whether 5V or 3.3V power supply is used. This resistor is provided in 5V position by default. In order to use BUZZ click with 3.3V development system, it is necessary to resolder this jumper to +3.3V position. J3 P1 1 7.
