hi guys,
it's my first time in here and i need help for a small project
i have a device which works on 12 V DC but i can't give 12V directly. I have to go from 0V to 12V in about 30 seconds. actully the device is for the physics department and theyv'e been using this device and when they start it they give 0 to 12V manually. they asked me if i can make a project which takes 12V from the power supply and feed the device the 12V gradually in about 30 seconds.
I want to make a digital circuit using microprocessor. if you have any idea please share it with me and if you can give me a thought about the right IC or the right potentiometer.
help me, please
