Arduino power: Measured 9.03 DC volts

Silicore AC/DC Adaptor: 13VDC/0.8A: Measured 16.52-16.59
Used the above adaptor initially assuming it was the 13 volts as stated, but smoke started to come through the breadboard. I quickly unplugged and measured the adaptor getting the 16+ range. That’s a good lesson in measuring things first.

ON
LED: 2.37
RESISTOR: 6.54

OFF:
LED: 0.02
RESISTOR: 0.00

POWER: 8.95 (STRAIGHT FROM WIRES)

Mistakenly connected one wire of switch to end of resistor lined up w/ LED (instead of other end of resistor). Made green LED turn amber. Basically started to burnout.

LED IN SERIES:
RED LED: 4.44/5 Looked like it may be slowly burning out
ORANGE LED: 4.32

LED IN PARALLEL:
BURNOUT
ADDED 220 RESISTOR WORKED
GREEN LED (CLOSEST TO RESISTOR): 1.94
YELLOW LED: 1.94
RED LED: 1.94

VARIABLE VOLTAGE W/ POT:
ALL THE WAY UP: 3.335
ALL THE WAY DOWN: 0.00
MIDWAY: 2.87
