I saw the other post on a fireworks igniter and all seemed slightly more complicated/complex than I needed. Besides, I went out and bought all my components already.
Based on my Honors Physics class lessons on circuits (about 5 days), I drew up a schematic and bought the necessary parts. However, upon putting them together nothing happened.
I've attached the schematic. The first switch is a shielded toggle switch like in a cool movie device. The second is a push-to-trigger button. The third wire is where the fireworks are attached. Normally, the firework would receive no current until the button is pressed, at which point it will receive nearly all the current. The only problem is that I do not have a 12V power source and don't feel like strapping 8 AA's together.
Thus, in scaling down the circuit, I came up with the equation that my resistors would need to be ~150 Ohms.
Sorry to beat around the bush (considering my question):
When I put my circuit together with 1 560 Ohm resistor and 1 2.6 V LED, the LED did not light up. Is this because the resistance is too high? Because I also connected another LED of the same kind, and it too did not light.
So in conclusion:

So in conclusion:
- Is 560 Ohm too much for 3V?
- Is 20 mA enought to ignite a firework (with 20 gauge stranded hook-up wire)
