I need a program and schematic circuit for this porpuse, let me sumarize it.
I want to program the output voltage from 0 to 12v, I want to have different voltages for the output, if for example I want to have 7 volts as output the circuit would provide that voltage. I want to program that in arduino pro mini, how can I do that?
help with voltage programming as output

Hi,
What resolution, what current?
DAC - Op Amp
Analogue switch + resistors
PWM + capacitors
Have you Googled something like digitally controlled volume control or similar

Hello,
DAC + OPAMP would be my choice.
v7 has a new DAC component allowing you to easily drive the DAC peripheral on-board some of the newer micros.
If your using v6 or a device without a DAC peripheral then you can probably get an external SPI or I2C DAC IC.
