Like testing pens at a stationary store it’s always nice to actually *see* the LED you’re considering purchasing – even if it does have a datasheet. So this quick video from Arrow Electronics is fun because they quickly scroll through ~30 of their through-hole LED offerings, from one end of the spectrum to the other. Because the difference for example between 565nm, 571nm, and 575nm can read on paper like too little to make a difference but in reality it could make or break your project’s look and feel (or even your contract with a client!).
Laura wanted to show people what wavelengths correspond to which color variations to help when ordering LEDs.
