My car i20 has vss signal range of 0 to 12 volt. It reads constant 6 v on multimeter from 12 v when car moves beyond speed 10 kmph. That's ok. It's average of 12 v.
Now, I want this fast output avg. constant signal to give constant output DC voltage say 12 v when the car attains particular speed of 40 kmph.
I would like a sketch of Arduino to achieve a desired output 12 v DC at speed 40 kmph. Say, pulse frequency is 500 per revolution; and total pulses at 40 kmph is 50000 say, and upon receiving these input pulses, the Arduino will only output constant 12 v DC.
Any inputs and corrections is always appreciated and welcome. Thanks.
