L293D & Arduino - Where I connect the 12 volt ground
« on: December 21, 2013, 05:25:48 pm »
Hi quick question, I was playing with the L293D Moter driver and Arduino and was wondering do I connect pin 8 of the L293D to a +12v and the ground to the ground of the Arduino. This is what I was doing http://learn.adafruit.com/adafruit-arduino-lesson-15-dc-motor-reversing/overview Thanks!

that tutorial uses 5V... where did you get 12V?

I know but I have a bigger motor that won't run on 5 volts

Where are you getting the 12V from? Are you powering the Arduino from the same 12V?

You would connect pin 8 to +12V, pin 16 to +5V from the arduino. Connect the ground to your 12V supply and connect the ground from your supply to the arduino ground.

DrLuke, no I'm using a separate 9 volt but thanks Nerull it worked!
