Resistors are electrical components that impede the flow of electrons. The unit of measure of resistance is the Ohm (Ω).
Also refer to the color code in the instructions (Figure 6).
A diode is usually made from two semiconductor materials. It causes electrons to flow in only one direction.
A capacitor is a combination of conducting and insulating layers that has the capacity to receive, hold, and release electrons.
Note that Capacitors are polarity sensitive, positive (+) and negative lead (-).
Transistors are transient resistors—they are made from semiconductor materials that enable a small current to control a larger current
LED’s are semiconductors that emit light in response to a small voltage without heat being produced.
