ADC and DAC

The world that we live in is analog; however, computers operate within the digital domain. This divide creates a need for a field of study known as data conversion. With that being said, welcome to the fascinating realm of analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC). This is where microcontrollers shine as the ability to convert real-world data such as temperature and light intensity into digital signals allows us to analyze and manipulate these signals, effectively allowing us to have digital interaction with our analog world. Smart devices and embedded systems where we take subsequent actions based on data analysis are common. ADC is essential for anyone interested in microcontrollers. In this chapter, we embark on a journey into the fundamental processes that bridge the worlds of analog and digital signals. These conversions, integral to modern electronics, empower devices to interact with and interpret the analog environment around them.
