Thanks,
So from what I understand Omh's law to be is V=I*R, so
R=V/I, but in this case we need the Voltage difference between the battery and the LED's forward voltage, so V= BatteryVoltage...

Agreed. But I guess where I am having trouble wrapping my mind around it is that when I to the math I come up with a negative value for R:

Vfbattery = 3.7
Green LED#1 FV=3.7
Green LED #2...

Okay I can get that, is that a difference between the NB3 that the video shows how to wire and the NB4? Because according to the math (that I am still learning with Omh's Law) the Forward Voltage of...

Need some help and I am not sure what I am doing wrong here. I am basing my work off this video of with a GGW and NBv4:

For the GGW, just like...
