I am looking to string LEDs in a series. I was wondering what type of power would be needed for this? Assuming each LED is 3.3V, does that mean for 4 LEDs I would need 13.2v? I have googled this just can't seem to find a straight answer.
update: I did some tests with the 5v output on the Arduino and I could do two LEDs without an issue which is expected based on the 5v output. When adding more, no light. How would one use say a 5v power source and power more than 2 LEDs or a 12v power source with more than 4 LEDs?
update 2: I was able to get the all to light up in parallel...I have 5 running in parallel right now. I am assuming this would work without issue.
Thanks.
