89c51/PIC based high voltage and low voltage cutout

[JatinderBir]

Hello friends I am looking for 89c51 based high voltage and low voltage cutout project with code
Or PIC based high voltage and low voltage cutout project complete with source codes for programming

Thanking you in anticipation

The high voltage and low voltage cutout can be made using simple comparators. no need for micros are there it will just increase the cost. for 8051 you have to need ADC ICs like ADC0804 or ADC0808. you have to program to get adc data and save it somewhere in controller and compare with some fix value. same is there for PIC but ADC ics are not required here because it have there own built in ADCs.

I fully agree with you, what I actually need is a micro based servo stabiliser project having Hi/Lo cut and 3 digit display for voltage indication
