I will require the model numbers of the TVs that are being used, if they are different, that is. It is also important to ask, where is the USB going to be plugged, the TV or external?
I will start by designing a bill of materials for the parts required, followed by a schematic and easy to read layout for hooking up the parts to your Arduino. After this is done, and you approve the layout, or request changes, or need questions answered, I will begin work on the code, and deliver it to you the next day, along with additional documentation. I will remain in contact for a few weeks/months afterwards making any changes, and fixing any bugs. If additional features are requested, I may request a small compensation, based on what is being requested.
