How does a microcontroller, which operates exclusively with discrete digital values (1s and 0s), measure a continuous, real-world analog signal like the temperature from a sensor?
Answer : The bridge between the analog real world and the digital world of a microcontroller is a crucial mixed-signal circuit called an **Analog-to-Digital Converter (ADC)**. Virtually all modern ... measurement like temperature, allowing a purely digital device to sense and react to the analog world....
