First Contact: Your Board, the IDE and a Blinking LED

10 Lektionen in dieser Stufe

1. What a Microcontroller Is and Where It Hides in Daily Life
   Explain how a microcontroller differs from a PC and name its three jobs: read inputs, decide, drive outputs. · Lab: Pick three household devices and list the inputs and outputs their controller must handle.
2. A Guided Tour of the UNO-Compatible Board
   Identify the USB port, power jack, regulator, reset button, pin headers, ATmega328P chip and onboard LEDs. · Lab: Label a photo of your own board and locate the power LED and the LED tied to pin 13.
3. Handling the Board Safely: Short Circuits, Static and USB Power
   Apply the handling rules that keep a board and a computer's USB port alive. · Lab: Set up a non-conductive work area and check the underside of the board for anything metallic touching it.
4. Installing Arduino IDE 2 and the USB Serial Driver
   Install the IDE and make the board appear as a serial port on your operating system. · Lab: Install the IDE, plug the board in and confirm a new port shows up and disappears when unplugged.
5. Selecting Board and Port, Then Uploading Blink
   Choose the correct board and port and upload an example sketch successfully. · Lab: Open the Blink example, upload it and watch the RX/TX LEDs flicker followed by a one-second blink.
6. Anatomy of a Sketch: setup, loop and Statements
   Describe what runs once, what repeats forever and how statements end. · Lab: Move the LED-on line into setup, upload and explain why the LED no longer blinks.
7. Changing Blink Timing with delay
   Control on and off durations by editing delay values in milliseconds. · Lab: Create a fast double flash followed by a one-second pause.
8. Reading Compiler and Upload Error Messages
   Find and fix missing semicolons, misspelled names and wrong-port errors from the output panel. · Lab: Break a working sketch in five listed ways and repair each using only the error text.
9. Comments, Naming and Saving Sketches Sensibly
   Write comments that explain intent and organise sketches in the sketchbook folder. · Lab: Comment every line of your double-flash sketch and save it under a descriptive name.
10. Sending Morse Code with the Onboard LED
    Combine timed on and off statements into dots, dashes and gaps that follow Morse timing rules. · Lab: Blink SOS, then your own initials, with correct letter and word gaps.

Abschlussprojekt

A personal light beacon that blinks your initials in Morse code on the onboard LED, with a commented and tidily named sketch.
