The PT4115 works fine for me, there might be an issue with your circuit. You can try lowering the PWM frequency, like 4k.

Where can I find the gerber files for the board and will a 3watts led work?

Thank you so much for your efforts, what you've done is truly incredible!
I built a DIY light bar with 3W LEDs and a PWM dimming driver. I even installed a Seeed Studio ESP32 C3 flashed using your program and software.
Everything works perfectly; I can adjust the intensity as I want.

The problem is that I can't adjust the sunrise and sunset times as I want.
For example:
I want to divide the sunrise time into 5 stages over 40 minutes:
1st stage: 7:00–7:10 AM
W: 0%
Red 20%
Green 0%
Blue 5%
2nd stage: 7:10–7:20 AM
W: 20%
Red 40%
Green 10%
Blue 10%
2nd stage: 7:20–7:30 AM
W: 50%
Red 50%
Green 20%
Blue 20%
2nd stage: 7:30–7:40 AM
W: 70%
Red 40%
Green 30%
Blue 30%
3rd stage: 7:40–7:50 AM
W: 90%
Red 40%
Green 30%
Blue 30%
Unfortunately, I can't use these settings in your software (see the image).

Easy mode sets the sunrise cycle to 30 minutes, from 7 PM to 7:30 PM, and I can't change it, for example i cannor put 7:10, 7:20, 7:30, 7:40, or 7:50 for optimal sunrise intensity, or any other time I want.
any suggestions please !

Thanks! Did u fabricate your own gerber and print it?
I used this driver 700mah, 3 leds 3w for 1 driver

Hmm those drivers where causing me a lot of problems...
I used this driver 700mah, 3 leds 3w for 1 driver
What powersupply are you using? 12v?
Did you do anything to them?
I used a 10k resistor from pwm to ground. Did you do that?

Its a pt4115 based driver
Just type 700mah led driver in aliexpress and you find dosens of these boards.

What kind of problems you had with this driver !? It's not a driver but a step down...
I use 24v 20a powersupply connected directly with step down driver without anything else

Amazing project. I'm in software engineering and did hw/fw in the past. You did a phenomenal job!! Wow. I'm geeking out over the github lol.
Did you ever evaluate your overall goal? Cheap aquarium lighting? How much does it cost you to build a light to something currently on the market with similar output? It'd be nice to see the outcome "they charge $x for something I made for $y" (and it's better!).
Congrats
