Hello... I'm Carlos... I can help you with your project... I have extensive experience in digital electronics, including Arduino and PIC microcontrollers... in RC (more than 20 years) in planes, helicopters, boats, cars and drones... and know how to design, build and test digital circuits (even have equipment for that). I'm right now in Miami, FL, where I can get any hardware fast.
Please tell me exactly what you need (how the 2 servos are correlated between them, and how are they correlated to the potentiometer... and the display - 7 segment 3 digit - will show the potentiometer value?)
Hope to talk to you soon...
