Im looking to build a vehicle speech interface similar to the mid 80's to late 80's nissan z car announcement system and would like any pointers on how to do so. what im trying to do is take vehicle signals such as seat belt warning, key in ignition, healights on, door open warning, fuel reserve light,e-brake set, etc. and take those signals and convert them to play a sound clip for example when the fuel reserve light comes on it would send a 12v signal from the fuel light circuit to the arduino which would then tell a sound processor to play a select MP3 clip assigned to that input, saying "Fuel Level Low" any help is greatly appreciated smiley-cool
for example when the fuel reserve light comes on it would send a 12v signal from the fuel light circuit to the arduino
I hope that you mean "to a voltage divider connected to the Arduino". 12V and Arduino are not compatible.
Google Arduino and SPEAKJET, and also search on here.
