12/02/2006 5:19 PM

My question is, i want to design and build a voltage detector to sound audio alarm and also display using a 7 segment diode

i will be happy if circuit diagrams are attarched

If you're trying to make a Do-it-yourself voltmeter...I know there are lots of tutorials for this sort of thing no webpages dedicated to small integrated circuits. I have done it using a combination of a PIC microcontroller and the Mikrobasic cross compiler that turns Basic into the machine code needed to program the chip. A programmer is needed to burn the program to the chip.

If it is any voltage above 1000Volts, then I could help you; even if you'd like to measure impulses, sine or harmonic voltages on power lines etc. (any voltage)

He said he wants to detect voltage not measure it, or does he...

I wish posters would be clear as to what they are asking.

John.

By implication of the use of "7-segment", it seems that he wants to see some numbers, rather than ONE LED... although he did use "detect" as well.

I agree John, posters could be clearer.
