I think that I will have to explain my whole story now. (The reason I want GET) . I have a school project in which I am making a Phone controlled WiFi Car . Basically I ripped off the Main board and made the necessary connections (switch) as explained by Gammon Forum : Electronics : Microprocessors : Switches tutorial . Then I created a 'game' (for Android/iOS) in Unreal Engine 4 which basically edits the URL (and loads it in background) when the input values from the gamepad are given.
I want to take the values (float , can be negative) fb (forward/backward) and lr (left/right) from that URL and use it to do any stuff that I want with it by storing the values in a same named variable in the Arduino sketch .
Let's consider a made-up Arduino URL "http://192.168.4.1/?fw=10.3&lr=2.8" . Now , I want you guys to help me take the part after '/' and store it in a String . I am a total NOOB in this field , so it would be really helpful if you could explain it too (just a bit).
Thanks in advance...
