My father and I are building a golf ball display case and I decided to add some LEDs above each golf ball. I will most likely be using a 9v battery to power the LEDs, but I want the option to use a left over power supply if it's possible.
Most power supplies I found in my junk drawer are 5v, but 1 of them is has an output of 9v DC, which I believe is what I'm looking for. What I don't understand is the amps, which it says are 1.1 amps. What does that mean to me? Since it's a 9v power supply will it use the same resistors as a 9v battery or am I missing a part of this equation?
BTW - During my prototype of this project I used a 9v battery and 330 ohm resistors. It worked as expected. If possible, I would like to use the same resistors.
Thank you for any help.
