Hey guys,
So I'm building a backlit switch box, in the style of aircraft panels. I bought some LEDs modules without looking at the datasheet...
http://optekinc.com/datasheets/OVM12F3R7.pdf
As you can see they're beefy. I want to PWM these LEDs. I was thinking I'd use a 555 timer chip and configure it to work as a PWM module. I'd then use some kind of electric switch I was thinking a relay or some kind of transistor, to actually switch the LEDs on and off because I know a 555 can't take that kind of voltage. If anyone has a good guide on the different types of transistors (MOSFETS JFETS Bobba Fetts) That'd be greatly appreciated.
