I have a 10w RGB LED package (3w per colour) and need to drive it so we can select:
White (all three together)
Yellow (red & green together)
Each of the LED's requires different voltages, and current limited to 350mA per channel.
I tried previously to do this, but with little success and just destroyed the LED's.
To limit the current I tried adding NSI50350ADT4G's, but they get VERY hot so dont think this is a usable solution. Also, as they get hot, the current goes down so not a great idea.
The LED's are common anode
Here's a link for the LED
I've uploaded an image of the original Chinese flood light controller, but dont want to use the IR remote. Must be via a single N/O switch.
I want to control the colour by pressing a N/O switch. Each time it's pressed, it changes to the next colour.
Once tested on an arduino, I plan to build it on a ATMEGA328-AU chip.
There are lots of circuit ideas out there about how to manage voltage and current for these LED's, but no guess work please. If you dont have the skill and knowledge, dont bid.
This is a re-posted project as it was given to a freelancer without the appropriate electronics knowledge to complete it properly.

Hi, dear! I saw your project. I am a interested in your current driver project. I can do it and i wold like to discuss the details. I will best. Thank you.
How r u?Buddy,,,Its me Imad, Have done 200+ projects regarding matlab, arduino, vb.net, html, php, pcb designing and raspberry pie. U will feel brotherhood..............................
hi, I go through your requirements, and found that i can do your project. i have experience in communication protocols and controller also. you may go through my portfolio and projects. thank you
Hi, Thanks for sharing the project requirements I am an adept arduino programmer and would like to work on this project Welcome to have an interview session for the project understanding Regards NG Services
I can definitely write the code for you, but have not had enough experience with specific parts to be able to tell you much about what to pick. Do you have a Mouser local to you?
