I'm trying to integrate the OEM dimmer into my LED project for an antique vehicle and I'm looking for some help. My prototype works great except the 7808 gets to hot I believe to be put in a small enclosure to fit the space I have available.
I'm using the 7808 to ensure a stable voltage is available to my Arduino Micro.
Most of the current draw, I believe, is going through my voltage divider that I'm using to measure what brightness the LED's should be.
I've tried increasing the resistance of R1 but I lose resolution and the ability for the Arduino to measure it.
I would love any feedback.
