Hi everybody,
We are making a project on sun tracking system using MC 89s52 and we used ADC 0808 to convert analog signal from LDR. All the circuit is working quiet good but there is a problem with ADC that a random voltage is generated automatically at the input of the ADC even when we did not apply any input signal to the ADC. Also there is the problem in output of the ADC that the digital number generated at the output is quiet different than the input signal but sometimes it is correct. Please help us as we have to submit our project within a week. The following are circuit diagram and program.
