I have never used LEDs before and am working on making a greeting card for an electrical engineer. I bought 2 Red LED Assemblies from RadioShack (product #276-0084) and I do not know what type of battery that I can use. I want to make something very simple, similar to a throwie, but I brought an LED with a built in resistor because I think resistors are supposed to be important? The information about the LEDs that I have:
"Red LED with holder and wire leads. Built in 1/4 W, 680-ohm reistor for 12VDC operation, 1/4" (6 mm) lens diameter, 2.78" overall length, including wire leads, 13/6" mounting hole.
Absolute maximum ratings:
Power dissipation: 180 mW
Forward Voltage: 12V
Forward Current: 15mA
Can I use one of those coin type batteries, like CR2032? Do I have to use a 12V battery? I want to use the smallest batter that I can, as I am making a greeting card.
Thank you to anyone who can help me.
