Hi,
I want to interface my AC voltage signal (which is coming from transformer) to ADC0808 with 89C51 microcontroller. so prblem is that if i will connect my transformer o/p +ve wire to the analog channel 1 then where should i connect my -ve terminal, i can't connect it to the ground because ground of IC is DC whereas my signal is AC. So please someone help me, i am damn confused....
