Disclaimer: I am still a beginner with electronics, but I'm happy to read articles.
Hi! I recently took apart a full-spectrum light I have (verilux vt31), as I'd like to redesign it as a IoT device for a sunrise alarm. However, I'm not sure how I'd go about figuring out what voltage/current to drive the LEDs with. I posted photos of the driver board, as well as a schematic below.
I was thinking of dimming it with a PWM signal from an esp8266, a RC filter, and a transistor. Would that be sufficient? Would I want to get a new power supply, or reuse the existing one? Also, has someone already created an LED controller that I could use?
Thank you for your time!
