What purpose do peripherals like timers and analog-to-digital converters serve within a microcontroller?
Answer
They enable the device to perform genuine sensing and interaction.
While early microcontrollers were essentially limited to simple counting and basic logic gates, the integration of peripherals like timers and analog-to-digital converters transformed them into tools capable of interaction. These components allow the microcontroller to bridge the gap between digital processing and the physical world, enabling the chip to sense external signals, interpret analog data, and perform timing-critical operations necessary for controlling external machinery or appliances.
