What Is a Microcontroller?

A microcontroller is a tiny computer built into a single chip. It contains:

• Processor (CPU)

• Memory (RAM & Flash)

• Input/Output pins

Microcontrollers are used in:

• Toys

• Remote controls

• Cars

• Home appliances

• Medical devices

• Smart gadgets

They read input from sensors and control output devices like LEDs, motors, and relays.
