Below is a schematic that I currently use to control my Ardu

Below is a schematic that I currently use to control my Arduino Uno 5 Vdc motor speed from variables 0-255. I want to be able to control and vary the speed/variables using my Laptop Computers Mouse \"ONLY\", instead of a keyboard input or using the potentiometer I currently have installed. Does anyone know of a program that might work for this? I want to be able to get rid of potentiometer R5 and use my computers mouse to control the motor speed/variables of 0-255. I DON\'T WANT TO USE THE POTENIOMETER; CONTROL MUST COME FROM MY LAPTOP MOUSE.

Moving the Mouse from left to right from Center would be great.

Solution

I found a .vbs script file that will mute/unmute and it works fine
but it does not solve the problem, it only makes it quicker to unmute.
