this is my first project with Arduino.
I have experience with many hobbies and also with programming languages, I'm an expert with Matlab and a bit with C.
I want to merge my experience into a new project and have the opportunity to learn about the fantastic world of Arduino.
The project is a flying boat with foils and an electric power motor.
I'm here to understand how to start and what to buy.
These what I need.
GPS ( I have already a BN-220)
channel for Radio transmitter FrSky R-XSR that communicate with SBUS or CPPM signal
3 ultrasonic sensors (I assume that is capable to measure the distance from the water surface, can someone test this?)
4 servo channels
1 esc channel
On Screen Display, OSD, on a video signal
smallest possible size
higher possible computational capability (I want to implement automatic regulation)
I will appreciate all type of help/suggestion you will provide to me.
but I didn't find anything that can reply to my question.
Can you give me an exact page of what you think can help me?
Well, you said "flying boat", so I immediately thought of Arduplane. Why reinvent the wheel?
Yes, all of the items in your list will work on Arduino. Probably not the Uno due to memory, speed and I/O limitations. Personally, I would start with the Wemos D1 Mini or ESP32.
Since this is your first project, I recommend that you buy the parts and start experimenting with them on a breadboard ONE AT A TIME. Most of the parts already have libraries and example programs in the IDE.
