Controlling two dc motor with blynk

Need Help With My Project
1

i am total begginer .i want to control two dc motor with blynk for rc car .i get it to work with arduino uo board and now i want to connect to android through blynk .i searched web but dont get mush help.how do i connect it to blynk .i have a ESP 12E wifi module.can some body provide me a sketch and code for the same

i got this code from this forum but no physical connection of wires given.

Here you are:

@prus1, once at home I’ll be able to provide you more details if needed

please provide more detail.and also code and setup of blynk .now checking on with arduino uno and esp 12e module.will see what happens

@prus1

Code snippet should be formatted. Edit your first post

Wrap the code by adding 3 Backtick: ``` symbols:

Example:

 ``` cpp <--put 3 backticks BEFORE your code starts  (cpp means C++ language) 

   //Put your code here
   //..................
   //..................

 ``` <--insert 3 backticks AFTER your code

**This makes your code readable and with highlighted syntax, like this:** 
//comment goes here 
void helloWorld() { 
   String message =  "hello" + "world"; 
}

@prus1,
The code, setup and some details are here:

The only missing information was the physical connections, but now you have it…

Keep in mind “One Axis Joystick” has disappeared… R.I.P…I’m still missing you my friend…:cry:
You will have to adapt just a bit the setup at APP side.

Kind regards
