1.POWER 1 for external supply.
Friends,I created an alarm system for my factory.The concept of the project is,when I pressed the button the horn will blow.The horn will blow in two types.
1.Blows continuously.
2.Blow with small interval time(Like LED blinking).
For power supply I used an battery.Because it will work under UPS connection.
1.My problem is when I connected all power point in circuit to UPS means,It hanging down.I checked the voltage across the PIC'S VSS and VDD,RESET pins their is 4.5V across it.But I dono whats the problem is..
2.I tried with another one supply.For PIC operation I used an 12V adapter and power supply from battery is connected to horn through realy to control it.At this condition it working fine.
When I tried to operate all with battery supply means it hanging down.
I dono whats the probelm with this circuit.
My requirement is I need to operate everything in battery supply only.
So please help to find out the problem in this circuit.
