Characteristics of a Microcontroller

  • Small and Low-Cost – Affordable and compact.

  • Dedicated – Performs one specific task.

  • Low-Powered – Uses very little electricity (about 50 milliwatts).

  • Embedded – Can be built into other devices.

3

​Applications

  • Used in:

    • Home appliances

    • Automobiles

    • Industrial machines

    • Mobile devices

    • Robotics

    • IoT (Internet of Things)

4

Popular Microcontroller Examples

  • Arduino Uno R3 – Widely used in education and robotics.

  • Raspberry Pi – For computing and programming projects.

  • Intel Galileo – Compatible with Arduino.

  • Asus Tinker Board – Advanced board by Asus.

  • GizDuino – A Filipino-made microcontroller.

Arduino Uno—Key Parts

  • Microprocessor (ATmega328P) – Executes the code.

  • USB Port – Transfers code and provides power.

  • Barrel Jack – Power via adapter (6–20V).

  • Reset Button – Restarts the board.

  • Power Header – Sends power to external parts.

  • Digital Pins (0–13) – For digital input/output.

  • Analog Pins (A0–A5) – For reading analog signals.

  • PWM Pins (~3, ~5, ~6, ~9, ~10, ~11) – Mimics analog output.
