planning a Wi-Fi controlled rc-car using Arduino UNO, ESP8266 Websockets or UDP

dear community

i am so glad to be here on this great forum - this is a great place. i have installed Armbian on

a. banana pi

b. orange-pi

and futhermore i will try to install it on Udoo Quad

at the moment i am workin on a new plan:  i am planning a Wi-Fi controlled rc-car using Arduino UNO, ESP8266  Websockets or UDP
the question that arises here. how would you decide?

i want to create an Arduino project about a Wi-Fi controlled (ESP8266) RC car using.
- with a tight budget you can’t really buy everything you need at once.  

what is needed:

    An Arduino UNO
    An ESP8266
    An L298N motor driver - with or without H-bridge
    An LF33CV 3.3V regulator
    An RC car
    Also batteries that meet your needs / much better: a power-pack

regarding the protocolls - not yet every decision is made:

- which protocol should i use!?
- WebSocket protocol or UDP-protocoll?

i need to figure out what else is needed to run this project with ESP8266 / NodeMCU one.

what is WebSocket Protocol?

WebSockets are a bi-directional, full-duplex, persistent connection from a web browser to a server. Once a WebSocket connection is established the connection stays open until the client or server decides to close this connection. With this open connection, the client or server can send a message at any given time to the other.

guess that i first will try out to go with the WebSocket-approach

but furthermore:  well after setting up all with a WebSocket-approach i afterwards will also try controlling the car with other protocols like HTTP or UDP to see the difference, if any.
    
    
what do you think?
