Customer fan controller to have fresh filtered air inside.

I camp in my car pretty often, but with two people
exhaling CO2, i was hitting 7000ppm of CO2. If I crack a window the mosquitoes will find me. So what better way to get ventilation than to use the hvac built into the car.

I programmed the button to mimic Olight’s brightness controls.

Double click for 100%, single click for on/off, press and hold for ramping up/down.

Only consumes 7 watts at 10% fan speed. Consumes 230watts at 100%.
