Hi Antonis,

Would using PWM help?  With PWM, the voltage level
oscillates between 0 and Vdd at a frequency that you
can set.  If your Vdd is 5V, and the voltage is high
60% of the time, and low 40% of the time, you can get
3V on average. Similarly, you can change your duty
cycle to obtain other voltage levels.

Cheers,

Wallace
