LED Driver Board

Description

This repo contains one-sided eagle files that can be used to build an LED Driver circuit for a car. The idea is to first low-pass the signal coming from the head unit, with a simple capacitor and resistor circuit. I found that I sometime wanted to adjust my crossover frequency, so I have used a potentiometer in the place of the low-pass resistor.

After filtering, the signal is amplified 100x and used to drive a MOSFET which acts as a switch to turn off and on the LED's. Video of this working can be found here (link coming soon).

I have only included the schematic and the board files.
