Hi to everyone , i want to build a rc car and try to drive and if possible also see,using an "app" maded with Unity,but i have a question,it is possible?maybe using a bluetooth/video board? thanks in advance .
Why do you think Unity is the right solution for this? As a game engine, I don't think it's really suited for this task. You'd be better off looking into a more generic app tool that communicates with a microcontroller or mini PC (like a Raspberry Pi) on the car.
Yes, it's possible but it's not an easy process. Some quick searching on Google shows that just about every example of it involves a custom circuit with a microcontroller (Arduino) or single board computer (Raspberry Pi) wired up to the motors. Someone has built an asset to assist with the Unity side of the process which is probably the best way to go if you're new. https://forum.unity3d.com/threads/arduino-unity-ardunity.433448/
Thanks for the advice,i will try to use this asset ,and as soon as possible,when i will take the pieces,i will open a new post for the project there is a way to connect a camera to unity??like this
