Hi, I have 4 3W (Combined) RGB LED's on the way for a project.
I want to be able to control the colour of all 4 LED's at once from an Arduino, but kinda stuck on how to do it. My limiting factor is that I need to be able to get all the parts from Jaycar Electronics - Better. More Technical. only.
I was thinking of doing it like this:
**broken link removed**
But there has to be an easier way? Could anyone suggest any ways I could do this with parts from Jaycar?
EDIT: Looks like my little 2N2222A's wouldnt be able to handle 700ma! Maybe I need to use 3 2N2222A's to switch some TIP41C's then ...
Cheers,
