Hi, I am basically trying to recreate this project. www.kaubonschen.com/sliwz/
What I am confused about is how to PWM all these LEDs. In the video the lights fade so obviously they are PWM. He mentions an amplifier circuit as well as the ShiftOut register. I will be using similar high power (1w per channel) LEDs so if anyone can give me insight to that as well I would appreciate it.
So how do you PWM with a ShiftRegister and how do you drive high power LEDs?
Sorry if this is a stupid question, but so far I am stuck.
