Car Reverse Horn Circuit Diagram

It is followed by amplifier ic ic2 and few other passive components.

Car reverse horn circuit diagram. The circuit is very simple to build and also it is very low power consumption. The ic1 reduces the car battery voltage to 5v. Circuit diagram and explanation in this car parking circuit we have used an ir pair for detecting obstacle and two lm358 dual comparator ics for comparing voltages. This is a project of a simple car reverse horn circuit.

The ic1 reduces the car battery voltage to 5v. Most of people have there own vehicles so i suppose this circuit will be very useful circuit for them this circuit is a car reverse horn if you can build your own circuit for your car i think that is great here i have used common music generator ic um 66 the out put voltage of um66 is not enough to make a good car reverse horn so by using two transistors bc148 and bel187 i have increased it. Comparator configured in non inverting mode and 10 k potentiometer is connected at its inverting terminal for adjusting reference voltage and ir receiver s output is directly connected at non inverting pins of all comparators. Here is a simple circuit that will produce a musical horn when ever your car is in reverse gear the circuit uses two ics for the operation voltage regulator 7805 ic1 and musical tone generator um66 ic2.

Circuit description of car reverse horn ic ctc2877 ic1 also called melody generator ic is the major component of this circuit. The diodes d1 d2 in combination produces an additional drop. It can be used with any vehicle that uses a 12v battery. The circuit will generate a musical horn when the car is in reverse gear.
