Hi. I'm new so please forgive any noob opps stuff on this thread. I think I'm posting in the right place?
Here's the scoop:
I've been doing some commissioned work that I need to add LED's to.They didn't come with many stats,so I'm just going on what I know.
I'm using 16 flat top blue 5mm LED's at 3.4V and I believe at 20ma?
1 White round 5mm LED at 3.4V again, I believe 20ma?
and 1 regular round red at 3.0V and 20ma.
I need to decide on a power supply. and I have some questions.
1) 12V or 9V power supply. Provided I use the proper resistors,will there be any difference in brightness? I'm guessing no?
2) can I connect the array like this?
*I made this diagram,it doesn't come out this way.
My last question
3)Are the LED's connected resistor(I'm aware that this can be on the cathode or anode side)Then anode to cathode to anode to cathode like the diagram? Seems like they should be anode to anode and cathode to cathode? Am I on glue here?
I am slightly electrical saavy,but I still get confused and I definitely have not done any for awhile,so I appreciate any input and I thank you for your time.
