Hi i can help you , i can design sytem bluetooth or USB low cost and i can control time of buzzer or any other parameter. design with Altium A14 see portfolio for samples of works.

there are many way to interface the buzzer with PC, but the easiest way and lower cost is via Bluetooth, we can make small interface with the buzzer to send the data you want to PC via Bluetooth module

Dear Sir, I have experience in design miniature circuits. I would like to provide you my expertise for you successful project. If you are intending to implement Bluetooth, I prefer you nRF51822 Microchip, which has Cortex M0 CPU with embedded Bluetooth Low Energy capability. nRF51822 comes with QFN 6mm by 6mm package, And WLCSP 3.50 to 3.83mm package. QFN package is much reliable, If its possible to fit in. However, nRF51822 require few external components like, Capacitors, Inductors, Resistors. If you are having difficulty with nRF51822, then I prefer you DA14580 as a backup solution. DA14580 Also has same functionality, but no external components. Also comes with 3.4mm by 3.4mm WLSCP pakage which ideal to your requirement. Once you come up with the hardware solution, your device must be programmed as HID device. Bluetooth Low Energy has profile call HID keyboard. Implementing HID key board in to your device and configure the Key values as (Left Mouse Button, Strg+F4, F4, Strg+R), You will be able to send selected commands in to PC. This is my brief explanation about how to send Key board values via Bluetooth Low Energy. Best Wishes.

Hi there. My name is Keith and I am a professional electrical engineer here in the US. I graduated Vanderbilt University with a BS in mechanical engineering. I now work solely as a contracting designer and freelancer. I am knowledgable in all sorts of microcontroller implementations, circuit design, sensors, mechanical systems, wireless and more. I am hardworking and understand that when all is said and done, my clients need a product that works well and done direct to your specifications. I invite you to have a look at my profile resume and portfolio. Thank you for your consideration! - Keith B

Hi, The simplest and the most cost effective way is actually use one of the ready transmitters / receivers where you can send any data you want. You will need to have a code for each item you want to send, on reception you will decode it and send it to the computer. Point to note: Your computer will not be detecting the attached device as a keyboard, so you will need a small program running to convert the received data to make it an input Hope this helps. If you are interested, we can work on this. Let me know. Thanks for your time and consideration. Best Regards, Venkat

Hello I am electronic engineer with experiecia in programming under different lenjuajes as java, java script, html, html5, wordpress, asp.net, c # database management, and programming mobile applications in PICs and dsPICs; PRODIA dsPICs certify thee with the physical part and the same program in c, would include code and schematic. I hope that my proposal is to your liking and feel free colsultarme for more details or questions.

I can make you device(with microcontroler) which simulate USB mouse or USB Keyboard ... how often do you plan changing what button press send? There is also option for BT device but is more complex and need also software on PC side...
