loop.wav -> Movement noise (loop)

Sound1.wav -> individual sound 1 (like Horn)

Sound2.wav -> individual sound 2

Sound3.wav -> individual sound 3

Sound4.wav -> individual sound 4

Delay.txt -> seconds for Motor stop if standing noise (0 for deaktivate)

Speed.txt -> max samplerate for loop.wav when max RC-input

description

To the engine start put the pin "Diesel" on gnd. To stop open the pin. Motor stop even if the standing noise for x seconds (in Delay.txt) is pending. By giving gas, the engine is started again. The sound start when the corresponding pin is set to gnd. The sound is played once
