The Wiren Board controller has a Buzzer (sound emitter) on board. The buzzer is powered by 5V and controlled by the CPU's gpio pin in PWM mode. The buzzer can be controlled through the sysfs interface of the kernel and various software on top of it. Management from the web interface, the wb-rules rule engine and python is now implemented. | The Wiren Board controller has a Buzzer (sound emitter) on board.
