@hek, thank you for that. I have had a quick look on his topics page and i will read through in more depth later on. I see he was the guy that created the IR Blaster than i was reading about a few months back. Looks a nice little module for universal controlling with IR. But again, by the looks of things i don't see any sort of PWM control going on with timers and what not. So unless this is handled through PWM pins (which i doubt because its all running through MOSFETS to power the IR LEDs equally) then it is just straight power to the LEDs when needed. I'm pretty sure that as long as the wavelength matches we're good to go without pulsing.
