    What code? I think the O/P wants the code written for them...
    With that schematic, a digital pot, a voltage divider, an A/D input, and a bit of trickery, a person should be able to hook up a PIC to auto-track/correct the output voltage...
    That's a handy little idea to have around...

    Ok, fact #1 - I'm no genius...
    fact #2 - good luck getting your code to compile and work in MeLabs PicBasicPro (any version)
    And...that code you posted...why would it stop for you? There's nothing in there to make it stop!

    Thank you very Much, actually i was trying that code in proton,by mistake i pasted.will delete now.
    Since you are a senior member of this forum, and you also understood what code i am searching for, Could you pls help me out. i need to adjust the voltage 0-10 with 2 buttons..
    Help would be appritiated..
    Warm Regards..

    Again...not a senior member of anything, and I don't use Proton.
    That code you copied was close...so, change it to fit PBP.

    OK, the 555 is good trick, but if you use an LMC66x series op-amp and a single +12 volt supply, you have a 0-10 voltage amplifier with 3 parts! May be 2 more to filter PWM from PIC...

    If you use a PIC with Hardware PWM (eg 16F628) then varying the Duty in steps of 10% from 0 to 100% (see HPWM command) will give you your ten steps. A simple filter on the output will then give you ten voltage steps from 0v (0%) to 5v (100%).

    I recall posting a circuit for an Op-Amp Voltage Doubler some time back. Do a forum SEARCH, stick that on the end of your filter and presto - you got ten steps of 0-10v.
