Electronics Worksheet: What Is a Microcontroller

Electronics lesson 21: What is a microcontroller? · Set 707 · 40 questions

Remember (One chip, one job): Microcontroller = processor + memory + input/output pins on one chip. Board parts: USB port (power and code), pins, reset button, power LED, main chip, voltage regulator. Write the program → upload over USB → it runs its loop for ever; power by USB or a small battery.
