This is an in-depth article (tutorial) for ADC, how it works, different types of ADC, error sources, sampling, and much more.
And this is when we start learning about the ADC peripheral and try to configure it so as to get this task done. Therefore, we need to read the analog voltage value using our digital microcontrollers. Just like temperature, light, pressure, and more other sensors are all analog. Most parameters and variables are analog in nature and the electronic sensors that we use to capture this information are also analog. We typically use an ADC in order to measure/read the analog voltage from different sources or sensors.
