Hello, I just purchased a Pan-Tilt HAT from Adafruit and I’ve been unable to find any information about how exactly a person is supposed to connect regular LEDs in order to get PWM brightness control working. Also, what is the current limit for regular LEDs?
I’m not expecting my shipment for a couple of days, so I’m just making guesses based on pictures. There doesn’t appear to be anything on the HAT itself capable of switching significant current (hundreds of mA), so perhaps the “Light Data” line is intended to connect to a FET that switches the LEDs? In which case, would the current limit just be whatever doesn’t adversely affect the RPi (trip fuse or brown it out)?
FYI, I’m planning on using a NoIR camera and want to provide IR illumination. I don’t yet know how many LEDs I need in order to get sufficient illumination.
Thanks for any help.
