How to connect 10W led + 12v Led Driver directly onto Arduino?

Hello there, can anyone give me an advice on connecting an 10W led + 12 volt drive to an Arduino Uno? it works but when i tried to connect to Uno it doesn't work anymore. Thankyou

Yes, without care, don't.

How did you wire it all up ? Can you post a diagram ?

NO pin on an Arduino output will accept 12V.

Hi Steve, I did it exactly the same as this video:

Does the LED work if you connect it, on its OWN to a 12V supply ?

If it does, you need to make a circuit, like Rick says, which will drive it with a 12V supply AND a pin on your Uno.

I used this product with 12v driver:

your uno will only supply 20mA current. Not enough to drive the 10 watt led. You need to control a relay or power FET to act as a switch for a separate power supply for the LED friverrt. Look up uno interface ccts.
