I’m thinking to use this on my setup. But instead of 1 LED I want to use a 50cm LED RGB SMD5050 LED strip.
Do I need then also the resistances and the blue thing above the TLC’s?
The power I will use not from the Arduino but from a 12V PSU (50A available).
I did search on this forum but couldn’t found any directly answer on my question.
If you use the TLC LED driver, then you would use one resistor to set the current level, and none on the LEDs. The TLC chips have 16 outputs, this is 3 8 bit shift registers, with shift registers not TLC LED drivers.
I used the TLC with LED strips in an instructable for making an ambilight (tv) clone.
It might be close enough to your thing that you can make just a few changes to do the thing you want to do.
