You can use a transistor to increase the size of your PWM signal, like this:

npn transistor say a BC458

1K resistor from +10V to the collector
emitter to GND
base to a 1K resistor to the PWM signal from the Arduino
connect the collector to the PWM input to the PSU.

Note that the transistor will invert the signal, so you will have to set the PWM output to 255-x rather than x. Where x is the desired output.

Sadly, thats one nice feature of VB that is not in C.

You'll probably end up using ifs and else ifs.

No, I think you can only have value.

If this is exactly what you want to do then,

Code:
if (menuActual % 2)
{
  // do even stuff
}
else
{
  // do odd stuff
}

If its code that you have the right to, then just ask for the source code.

Sorry, I've got to ask.

What is the application?

HA! Another opportunity to plug my new book!

30 Arduino Projects for the Evil Genius - Simon Monk.
http://www.arduinoevilgenius.com

This has projects that illustrate sensing, displaying driving motors / servos etc.

It explains how the electronics work pretty much from first principals. Ditto the programming.

A present for your patient partner who lets you spend your time on this stuff.

Or, a present for a would-be partner, who may make you want to stop doing all this.

I would like to add to the list:

30 Arduino Projects for the Evil Genius - Simon Monk.
http://www.arduinoevilgenius.com

This has projects that illustrate sensing, displaying driving motors / servos etc.

It explains how the electronics work pretty much from first principals.
It doesn't even assume that you know Ohm's law.

But then I'm biassed. Seriously I did have people like you in mind when I wrote it.

Yet another PCB making tutorial. But this includes a UV LED light box.

With such cheap clones on eBay, how popular are the official boards?

They are saying geek is chic.

Real hackers use a command line.

I bet quite a big proportion of the people on this forum come from a software day job.

There is something very satisfying about some real electronics and only having a few dozen lines of nice easy code to make the Arduino do what we want.

Good luck with the project.
