Hi there,
I have a generic car audio head unit which allows for reading of the steering wheel control buttons and mapping them to the unit, the only problem is there is a wire which requires 3.3 volts to make it run, but finding a wire like this in the car is near impossible.
So does anyone know an easy way to regulate the ~13.8 volts to step down to 3.3 volts?
thanks![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
