The above provided circuit can be used to avoid cheating since it depends on the push of a button.

Analog to Digital converter circuit using ADC0808

The Analog to digital converters are very useful in a digital system where the conversion of raw analog signal to digital data bits possess a notable significance. ADC's are also quite familiar in several microcontrollers, but using a ADC in micrcontroller requires programming skills and not everyone love to go in to programming. The circuit shown above will offer a solution for those who don't have any sort of programming skills.
