I am building a led mood light with a high power RGB LED (30W) using 3 constant power supplies for each color.
These are the items I had in mind (but open to suggestions):
Each color will be controlled with PWM by arduino. So far so good, the problem is that the bc337 transistors I have can only go up to 800ma so I need something significantly beefier. What is my best and simplest option here? I'm not very knowledgeable in electronics so simplest solution would be best.
