Motordriver w/ L293D

I've built last week a motor driver pcb with the driver L293D. Enjoy!

This is my finished motor driver board with the IC L293D. Their operating voltage is 5v - 36v (Vs) and 5v (Vpp). Important: The Enable-Pin must connected to a digital pin of an Microcontroller, like arduino. The enable-pin must be high, before you using the motors! Have fun!

    CAn you show it connected to the arduino uno please. I am new and not sure what to do.

    @Pyercubed: Hi first of all take a look at the datasheet of the motordriver here: www.ti.com/lit/ds/symlink/l293.pdf Now connect VCC1 to your Arduino 5V output. VCC2 to an external power source. Connect 1,2EN and 2,3EN to an Arduino output that don't supports PWM. We need those for 1A-4A. If you are all wired up connect your motors to ouput 1Y-4Y. Use also a capacitor between power source and ground (10nF).
