A diode

Diodes may be the simplest application of semiconductors in electronics. This is getting ahead of ourselves, but they are essentially transistors with the base and collector tied together. In practice, you can think of them as valves that allow current to flow in one direction (the way the arrow points) and not the other. The only penalty is a 0.6V drop across the diode. If the voltage on the upstream side of the diode does not exceed this, current will not flow. If it does, it will. Done!
