-Speed-dependent engine noise only one motor-loop wave file
-4 individual sounds
The following files must be on the SD card
start.wav -> engine start
shut.wav -> engine stop
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
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 or Sound 1 and 2 reading Rc signals to start the Sounds (#define RC switch). The sound is played once.
