Microcontrollers have become very useful in embedded design as they can easily communicate with other devices, such as sensors, switches, displays, keypads, motors and even other microcontrollers. A microcontroller is basically used as the brain or intelligent processing unit to control other devices connected (interfaced) to it in embedded systems just like a PLC is in industrial automation. Interfacing a device with a microcontroller in simplest terms simply means to connect a device to a microcontroller. This article will make it easier to anybody with very limited experience in electronics to learn how to interface different sensors widely with a PIC Microcontroller.
