Rise of microcontroller computation – By Aditya Abeysinghe   Microcontroller A microcontroller is a single Integrated Circuit (IC) that uses memory and input and output (I/O) inside it to compute. It is a new technology which uses a different methodology to compute using fewer external devices. Most of the hardware required for computation is built-in and often only power and data from sensors and is required to perform computations. Microcontrollers are less costly and use less power compared to microprocessors. These devices are used to process data external to a device with minimal input. Therefore, they are embedded in electronic devices such as air conditioners and are used for research activities. Microprocessor A microprocessor is a single IC chip that uses memory and I/O external to it to compute. Memory (primary and secondary) is external to the microprocessor and it is connected to the chip with bus controllers. Microprocessors are ...
