HI there,
I have a project to be done at school: I have to build a traffic lights to monitor de volume in discotheque etc... The traffic light should consists of a bright yellow official traffic signal with Red, Yellow and Green as standard. A microphone built into the unit monitors the sound in teh disco. For low levels of sound, the Green light is illuminated. As the sound level in the monitored area increases, the Green light will go out and the Yellow light will come on. For greater levels of sound above that which causes the Yellow light to light, the Yellow light will go off and the Red light will go on. Please bear in mind that the International standard of SOUND should be respected >65 dB. Please help me with the circuits and also a little explanation. THnx in Advance
