Hello all! I've got a super simple LED circuit that I've wired up as my first foray into DIY electronics. Unfortunately, it doesn't seem to be working quite right, and I'm not sure where I went wrong. It lit up alright for a bit, but it seems to have stopped. I checked my wiring with a multimeter, and everything seems to work alright, but no light. I have a feeling I picked the wrong resistor and burned out my LED, but I don't know for sure.
I'm hoping someone who knows what they're doing can advise me so I can move forward rather than being confused and discouraged.
Here's what I've got going on (If I've left out any necessary information just ask):
The circuit is running on a 3v lithium coin cell battery (cr2032). Following the positive lead, it goes through a small tact switch, then to a 68 ohm, 1/2 watt, 5% tolerance resistor. Next it hits the LED. Here's the details off the package:
Intensity: 80mcd (typical)
Wavelength: 660nm (typical)
Viewing Angle: 154 Degrees
FW current: 20mA
FW Supply: 1.9v (typical), 2.4V (max)
Coming out of that, there's a second tact switch, and then into the negative of the battery.
Hope someone can help me out!
