ANALOG LED DIMMER

I have a COB LED 50W Lamp Light 12V Circular LED Bulb powered by a 12V battery. I also have a ARDUINO MEGA 2560 (if needed).

I would like to linearly increase the intensity through the COB LED with variable programmable time steps. This is used to simulate the sun rising light from dawn so i can't use PWM technics, just analogical. I can handle the programming but i need some help to figure out the hardware.

Can you please clarify what issue you have with using PWM? In most cases, analog regulation cannot be used with LED because of the non-linear characteristics of LED and the significant fluctuation of parameters caused Lagi

Yes you can use PWM and it is almost exclusively used for LED dimming. Simulating a sunrise using PWM is simple if you use the Mega. I can provide you with a simple wiring diagram and some sample code. Regards, Jim
