Hello,
I am trying to set up simple led circuit nothing fancy just want to be able to light them.
A little back info: This is my second time trying to finish this particular project and I am very newby as my name implies so bear with me. I recently lit up an array of leds and it worked for about a minute until they started burning out one by one. I think my main problem was that I only used one voltage limiting resistor for the entire array. technically it should have worked but it is very unstable.
Also, I noticed that my battery which has a nominal reading of 9v was actually 9.9v when hooked up to the multimeter. I didn't notice this until after my leds start popping. Does anyone know if voltage on batteries is supposed to change much? If so how would I deal with this problem? I'm trying to get my measurements as exact as possible in order to have my leds as bright as safely aspossible.
This is a drawing of what I have my circuit set up to currently, any suggestions would be greatly appreciated.
