Any ideas on making a light that would light up every 3000 miles?
Radio21 said:Many newer U.S. cars, have a sensor that provides a pulse per rotation, it is used by the on-board computer for speed, where it measures time between pulses. This could also run to a large digital counter which would count up to a value, and trip a registered led or something if the count exceeded a value. The user could reset the counter when the oil is changed.
