Vary DC Voltage With Potentiometer?

Is there any way to use a potentiomiter to very the dc voltage output? and what output is the voltage going too? I'm doing a science fair project and I really need to know please help! confused

Idea of a voltage divider. A pot is a variable resistor with two legs that combine to make the full resistance value of the pot.

You can vary the voltage from the EZ-B using the PWM between 0 and 5 volts. It won't power much, but it's used as a signal.

If you'd like a pot to vary the voltage, then you'll need to ensure the POT can provide enough current. What will you be powering?

If you need to vary the voltage from a POT, than using an adjustable voltage regulator will do the trick.

If you provide us with more information, we'll be able to help you:)

Never mind I didn't know you can use PWM to vary the power and I am powering a cochroaches leg. I found that depending on how muc electricity is put in the cockroaches leg you can makeit move. Don't worry the cochrach won't get hurt.
