I'm doing a project using PIC 18F4550. I want to know how can we control the current from a power supply using the output of the PIC. ie, Just give me a circuit that can automatically vary the current from powersupply using pic output. One way is to control a potentiometer using pic output. or we can control the voltage keeping the resistance constant.

expecting your whole hearted help...
