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

[Martin_179]

dear community


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

Which protocol to use should be the least of your worries.
You can go two ways (at least):
- a web server in the car with buttons for left/rights/stop etc;
- custom server doing the same, with custom client.

I'd start with web/HTTP, until you have you car ready, and then think about optimizations.
