I'm pretty clueless. This is just a personal project and I desperately need some help.
I am trying to build an LED flash unit. Just like a camera flash unit but less powerful, a lot simpler and lower voltage.
My idea is this: A 3v coin cell charges a capacitor. A button pressed allows the current to flow from the capacitor to the LED and the LED glows only while the capacitor is discharging.
If the switch remains closed, the LED goes remains off after the capacitor has discharged. If the switch is opened, the LED goes off after the capacitor has discharged and the capacitor begins to recharge.
Can anybody help?
