how to control 4 motors with joystick???

hi guys,i want to control 4 motors with 1 joystick,and i have the parts,parts are-l293d chip 2 of them,4 motor with wheels,joystick,breadboard,arduino uno
a little help will be needed for the coding

The coding depends on what you want to do with your parts list.

yeah,i want them to move forward,backward,left and right,basically a car

Does it have physical steering or skidsteer type steering?
