i don't understand how to program the Texas Instruments L293NE i did find a prebuilt program but it controls 1 motor not 2 can someone take this program and try to tell me what to do? http://db.tt/izBnb0r

That chip can not be programmed using the Arduino IDE.

It can be connected to the Arduino, and the Arduino can be programmed to control the chip.

In order to do that, we need a link to the data sheet for the chip, and a schematic that shows how you connected it to the Arduino, to the motors, and to the power supply (or supplies).

A 293 is just four half H-bridges, so the code to control two motors is the same as the code to control one motor, but the wiring is different.
