Description of the Situation:
Hello, I'm doing a car with Arduino, which is controlled by a Analog Thumbstick attached to another Arduino. I already have the code to read the analog values and send a character to the car, because previously it used to be by Bluetooth. Now, we are asked to do it by Wifi and Ethernet. The Thumbsticks will be attached to the Arduino with the Ethernet Shield and this one, connected directly to a Router. This Router creates a Wifi network. The car is over an Arduino Uno with a Wifi Wizfi210 Shield. I already made the Wifi shield connect to the network created by the Router, so the 2 Arduinos are in the same network and always with a unique IP setted by me on the Router's config.
Problem:
What I want is the code for each Arduino to communicate between them. On the Ethernet, just send a Char to the Wifi... And in the Wifi, read the Ethernet's Char. Is only that, but I have almost no knowledge about creating servers or clients.
Thanks.
