I want to control a single LED (Osram LE CG P2AQ) with an Arduino (simple on/off). What is the best way of achieving this?
Simply connecting a 10A current supply via a Mosfet?
Using a Buck Converter module that can handle 10A and use the PWM just for on/off?
It has to be very fast (as in milliseconds), thus a relay is out of the question.
Thanks for any pointers or concrete advice
Edit: I mixed up my unites. msec, not µsec.
