Want to use Arduino in my truck for various projects. Keep reading horror articles about the '12v' power available.
Since 14v+ is normal when charging and Arduino maxes at 12v, could I use a resistor to lower voltage to 6v and a Max809 chip to filter noise. This would seem to be a low cost way for protection,
I am a novice on reading circuits much less design.
Thanks for any advice.
