C9: Arduino / RPi Pico Advanced + Sensor Interfacing
  1. What is a Microcontroller?

     

    • A microcontroller is a small, self-contained computer on a chip.

       

    • It has three main parts:

       

      • CPU — runs instructions like the brain.

         

      • Memory — stores programs and data.

         

      • I/O Pins — connect to sensors, LEDs, motors, and other devices.

         

    • It works without an operating system — it just runs the program you give it.
