    I need a design of a device that is able to generate random frequency in a setted range (for example 50Hz - 200KHz). This device should be connected to a piezo or a vibromotor. An amplifier needs to increase or decrease the intensity of the vibration. With an User Interface is possible to setup the parameters (frequency + intensity). Please note: I need only schematic and PCB design.

    The design target of this project is to create a PCB which can be mounted in a stereo audio power amplifier for professional applications, allowing to remotely change the volume via a web interface. It further allows a few other basic settings of the amplifier, and also the display of the basic amplifier status via the web interface. The signal path of the amplifier remains analog, hence a digital...
