Yeah, it’s time to get back to some LED magic. In this experiment we’ll build an LED brightness control. We’ll be able to see the LED light up just a little or a whole lot.

    Ohms and volts are actually measuring two different things. Ohms measures resistance to the flow of electrical current. Voltage measures electrical potential, also called electromotive force. You can think of voltage as trying to “push” electrons.

    Approximately how many ohms is a volt?
