Two textbooks and 5 youtube videos and you were the only one who specified the direction of the stinkin diode. Thank you! Was going out of my mind! Larry,

I had procesing open in sted of arduino :Þ sry again ... thanks r. hahahaha. sorry for the haisty comment. I had procesing open in sted of arduino :Þ

sry again …
thanks

I get this error
“cant find anything named output”

im new to all of this so I hope im not being stupid about this..

thanks.

Such as making two of the Arduino boards shown above and connecting it to a interface to time them speeds and distances.

But I just set it up and it worked fine with a simple switch :) thanks a lot for your info Actually I guess this wouldn’t work so well on a robot who you aren’t interacting with!!

Basically switch which way round the wires are connected.. Surely to make it go CW or CCW, you could add a DPDT switch between the wires that go “to motor” and the wires from the motor?

I'm using the TIP120 because its emitter pin uses no more than 5 Volts which is what you're looking for with the Arduino - so you could find any part that has the same properties and it should be OK. You'll see its collector pin can handle around 60 Volts (I think). If you have any issues I have a few spare TIP120's :) TIP121 should be fine if you look at the datasheets they’re basically identical.

Would it be possible to use a Tip121 instead? Im living in Ireland and am finding it very difficult to get a Tip120. Would it be possible to use a Tip121 instead?
