Hello EE Stack Exchange!
I am a mechanical engineering student that needs some help with a circuit. I am have an extremely limited background in circuits so I have to apologize in advance for this question. This is the circuit I was able to get together to turn a light on and off using a transistor and relay:
This is great and I think it would have worked but the requirements changed before I could test this. I now need 2 LEDs in parallel. This isn't ideal since I only have access to a power supply of 6v for two 3.3V LEDs in parallel. This is on a device that has a 6v power supply and a 3.3v arduino. Two LEDs in parallel can consume 1.4A to 2A at this voltage. What is the best option here for getting parts to support a circuit like this? Do I get a transistor like this? Do I need to change the circuit further?
Any help is appreciated.
Specific parts used in previous version are:
KEMET EC2-4.5NU Relay
LD1117V33 Linear voltage regulator
CREE XML2-W318 LEDs
