    Would you clarify a few tignhs? Do you want to drive all red, green and blue LEDs of 8 RGB LEDs (that will take 24 outputs, so 8 more than the 16 provided by a TLC5940). What RGB LEDs are you using? We need to know if they are common anode or common cathode (your wiring looks like common cathode, which won’t work with a TLC5940, which can only sink current. Common cathode will need a different chip). Also blue might not switch on using 3.3V, so will need 5V. Must it be through hole electronics (e.g DIP), and not surface mount. Do you care if it uses 3 chips instead of one? Nov 8 at 0:37
