First Arduino Project (Analogue Output)

Projects General Guidance

Hi,

I hope i have put this in the correct section, if not sorry about that.

I am planning on my first arduino project, i havent purchased anything yet, so im after some advice. My project is to ramp a voltage between 0-6V and read the output voltage and current back from a device under test.

Can anyone suggest a arduino board or kit that will start me on this project?

Thanks

James

My project is to ramp a voltage between 0-6V

The arduino will only provide a 5V output. If you do need 6V then you need to pass the output through a transistor connected to a 6V power source.
The arduino provides a PWM output, you can smooth this to get an analogue voltage.
If you don't know about PWM then see:-

Hi,

Thanks for the reply. Just been playing around with a friends board and i think i have something working using the examples.

Many thanks
