- LED - small side = long leg = positive
- Connectors - red wires positive / black wires negative or ground (why GND? GND = grounding for discharge)
- Resistor - if you didn't have it the LED would blow / it makes sure the led does not draw all of the 5v current / 220 Ohms Resistor - red red brown is 22 *10
- Resistance is calculated in ohms. So how do we figure out the current?
