I'm stuck in a project.Quick description:
I want to illuminate my desks.
I bought this 5050-clusters for that (18pcs):
Front & Back:
Common Anode, for 12V
I try to use 4 TLC5940.
Ch0 -> LED1-Red
Ch1 -> LED1-Green
Ch2 -> LED1-Blue
Ch3 -> LED2-Red
Ch4 -> LED2-Green
Ch5 -> LED2-Blue
5 "Cluster" on each TLC (Ch 16 not in use)
Look like this (Front & Back):
(Missing on picture: Cables to the LEDs and some soldering... but you get the idea)Power:
The TLCs get the Power from the Arduino (5V), the leds by a lab-powersupply - 12V
Ground from power supply and Arduino are connected to each other.
All anodes are connected directly to the power supply.Problem:
The 1st TLC works fine, doesnt get warm at all, just as it should be.
The 2nd TLC doesnt work at all
Doesnt get warm either, but the LEDs just dont light up.
For testing I used the "Basic_Use" Script from the TLC Library. I also edited the tlc_config.h (#define NUM_TLCS 2).
Currently there are only LEDs on TLC 1 & 2.
Can anybody help? Do you need more information?
Thx a lot in advance
