CAR HORN WIRING CIRCUIT

Car Horn – Circuit Wiring Diagrams
Circuit operation. To obtain a realistic car horn sound, two different tones mixed together are necessary and the interval they will form should be a so called minor third (in musical terms). This is implemented by two 7555 CMos Timer ICs wired as astable multivibrators and generating a square wave of about 440Hz and 523Hz respectively.
