Crystal 5mm Green LED Light Emitting Diode

What is this?

Who doesn't love LEDs? They are bright and blinky, or soft and elegant. They're festive! They're colorful! They're everywhere and they're a lot of fun. We love LEDs when we write tutorials because most of electronics hackery is hidden in chips, or goes very fast and we can't see or sense it without expensive equipment. But LEDs are easy to see for everyone - this way we can visually identify what is going on inside our microcontroller.

Specifications

• Crystal 5mm Green LED Light Emitting Diode
• Lets begin with an anatomy lesson…The Parts of an LED!
• It's all a little confusing - we often have to think about which is which. So to make it easy, there's only one thing you need to remember and that's the LED wont light up if you put it in backwards. If you're ever having LED problems where they are not lighting, just flip it around. Its very hard to damage an LED by putting it in backwards so don't be scared if you do
• If it helps, refer back to these photos and diagrams or print them out for your reference
• 5mm LEDs! Green, Red, Blue (in a clear case) and InfraRed (in a bluish case)
• When we first started making electronics in the late 90's, we bought some 5mm blue LEDs and they were $3 each. Now you can get easily a dozen LEDs for that price. Life is good!
• LEDs come in all sorts of sizes as well. Here is a photo showing a 3mm, 5mm and 10mm LED. the "millimeter" size refers to the diameter of the LED. For example, if you need to drill a hole in a box for your 5mm blinky LED, the hole size should be 5mm, and you'd need a 5mm drill bit to make it. 5mm are the most common size you'll see, and they can be extremely bright!
• Green 3mm, Red 5mm and White 10mm LEDs
