LEDEdit

LED is a light emmiting diode. It only allows 1 direction of current, and it lights in that direction. The current must be limited by other components in order to not damage the semiconductor (which makes the light). Newer LEDs in Snap Circuits have internal resistors inside, but the older ones don't have resistors.

DiodeEdit

The diode (D3) conducts or turns on when the voltage at the anode is 0.7V or greater. It will only allow 1 direction of a current. The current must be limited by other components in order to not damage this part and/or make a short circuit.
