According to this blog post: Controlling high power (or high number of) LED’s with an Arduino | The Custom Geek or this post: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1270486354
to control 8 RGBs with 1W seperatly i would need:
24x TIP122
8x 1W RGB LEDs
1x constant current supply
hand full of resistors
1x arduino compatible board with at least 24 I/O Ports
and sufficient cooling for the TIP122
Could that work as a head start?
Is it true that i could also use ports without PWM to control the transistors? is this as good (same effect) as the hardware pwm?
Thanx
