Product using microprocessors generally fall into two main groups, the first category belongs to high-performance microprocessors and the other is a microcontroller.
An Arduino is a microcontroller board that comes with pre-tested software and hardware libraries and also its integrated development environment. It is used for building electronic projects.
Arduino boards, including the Arduino Uno, use an AVR AT Mega microcontroller. Arduino is used for the home automation system and IoT application. An Arduino can accept between 6V and w20V through the direct current.
The 8051 microcontroller is just a single microcontroller that belongs to the 8-bit family of a microcontroller. The 8051 microcontroller has a total of 128 bytes of RAM. The intel 8051 operates safely at a voltage between +5 volts to a maximum of 6.6 volts. An 8051 microcontroller is used in a remote control, auto engine, control system appliance and so on.
