Driving LEDs

An interesting video from Element 14 regarding driving LEDs.

Hi Bob,

Great watch, thanks for putting this on the forum, alongside Core’s Ohm’s law guide this is a surefire way to get long life out of an LED!

Hi Liam
Yes I thought it would be of interest, especially to newcomers. The author has done one thing that could be confusing to the uninitiated though. He has expressed current in mA instead of A. Plugging his numbers in mA and V into the formulae would give a direct result in kΩ which could cause confusion to aforesaid newcomers. Us old heads would spot this eh ???
Cheers Bob
