To realize a product, it is necessary to combine hardware, that is the equipment itself, with software (a Program) that runs its functions.

By changing the program, adding or removing functions can be carried out easily.
For example, in the case of a rice cooker,
Control of boiling rice quantity,
Clock control,

The rice cooker is controlled by making a program and embedding the program into the microcontroller.
