Hello. How can I use 5630 SMD LED from an LED lamp with Arduino? Can I connect this directly to a digital pin?
No. It seems these LEDs can draw 100~150mA. Some types of Arduino pin can provide 40mA per pin before being damaged. Many types of Arduino can supply less than that, like 12mA per pin.
You will need a driver circuit, probably a constant-current driver.
For a single led something in the 300 - 3.3K range connected in series with the LED to a UNO pin should light it. The lower the resistor the more current the brighter the led. This is deliberately vague as you did not tell us the color or the Arduino you are using. Be sure to stay under 10mA.
Hi there,
You can't directly connect a 5630 SMD LED to an Arduino pin due to high current requirements. Use a transistor to control the LED:
- Transistor Setup: Connect an NPN transistor:
- Arduino pin -> 1kΩ resistor -> Transistor base
- Transistor collector -> LED (with resistor) -> Power supply (+)
- Transistor emitter -> Ground
Hope this helps!
