We are developing a new hardware product that will use Arduino boards with small LCD display screens. We have the circuit design done, but need some help with the C++ programming for a simple user interface that has customizable menus. The menu will select devices to be controlled by switches and relays. We need someone who is an expert at Arduino programming and simple user interface design. Please no inexperienced developers. More details will be provided after a non-disclosure agreement is signed. Please provide examples of your past relevant projects.
