Automatically Varying Voltage Power Supply

[enthu-techy]

i need a automatically varying voltage power supply which varies from 0-30V by 0.1V step.....should i use a adc and micro controller or can i use an adjustable voltage regulator and vary the resistance....if i have to use only the adc and microcontroller...then what ic and µc should i use...and what is the program i should feed into the µc.... please help ... very urgent

Why is it urgent? What microcontroller are you familiar with?

can i use an adjustable voltage regulator and vary the resistance.

Probably. A plain old LM317 will work in that range. What's your application?

its urgent becoz ...i need it for my project....i am familiar with 8051 ......and am also interested to do with PIC
