2 Dof Miniature Simulator

[bitMario]

I purchase 1 arduino 2560 mega , 3 x l293d shields and 3 step motors 28byj-48
I install the sdk and the arduino on my windows pc and everything is ok
I plugin my board and i play with some leds and worked fine.

Now I want to connect the 2 stepper motors to my l293 shield and to start to do some movement. How i will connect the stepper to the L293D shield?
