 ===== Resistor 3 (Yellow, Purple, Brown, Gold)=====
 Resistor Value: 470 Ohms
 The brightness is almost as bright as the on with resistor 2 which is weird becuase resistor 2 has a greater resistor value and the bulb connected to resistor 2 should be less bright compared to this bulb. Again, it may be becuase I did not connect the wires properly on this circuit which resulted on the electricity not flowing properly.

 The amount of current recroded at the resistores decreases as the amount of LEDs increases.
 The totoal current stays about the same.

 The resistor controls the blinking speed because, the resistor controls speed the capacitor charges at. If the charging of capacitor slows down, the LED will need more time before it can turn on. I can add resistance by adding a resistor with greater resistance and doing that would slow down the current. To change the amount of resistance without swapping out parts, I can use a potentiometer.
