0 - 10 volt analogue output from Arduino

I need to be able to provide a 0 to 10 volt output from my arduino as a signal (small current) to the analogue input of an electronic speed controller of an electric motor.

I am playing with an LM324 op-amp but cant seem to get it to work. (can only get the output down to 9 volts minimum with no input voltage applied! )

Has anyone done this or know how to do it?

A little searching goes a long way: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1216381158/5#5

It was anwered fairly recently.

Thanks for that Oracle.

I did do the search beforehand and came up with nothing.

I have just run it again with the following phrase:

"0 - 10 volt analogue output"

The only items that come up are my OP and your response.
