I’m relatively new to the whole hardware scene and have a couple of questions on a strobe flasher controller I’m working on. I have the program working for the most part, beyond some final tweaks I have in mind.
Anyways, on to my questions…
First, I need to switch on/off a device (LED Module) that is 12v up to 2A. There’s a need to toggle it on/off in 10 to 20ms intervals. From my limited experience, it seems like a MOSFET is going to be the best method to accomplish that, but I’m not sure how I would connect it up between the +12v source, the Arduino Pin, and the device.
There’s a secondary idea to also step the voltage down to 7 to 8v. That would be a switched/photosensor’d situation though to control the brightness at certain times.
Is there any reference materials that would help me figure this out?
