The Serial Monitor: Making Your Board Talk and Listen

10 Lektionen in dieser Stufe

1. Opening the Serial Monitor and Printing Text
   Start serial communication at a chosen baud rate and print lines. · Lab: Print a greeting once and a counter every second; then mismatch the baud rate and observe.
2. Printing Variables, Number Bases and Tidy Columns
   Format output with print, println, tabs and DEC, HEX, BIN. · Lab: Print a table of numbers 0–15 in decimal, hex and binary.
3. Tracing Program Flow with Serial Prints
   Place prints to find out which branch runs and what a variable holds. · Lab: Locate a planted logic bug in a given sketch using only print statements.
4. float, char and bool: Choosing the Right Data Type
   Select types by range and precision and avoid float pitfalls. · Lab: Print the result of dividing integers and floats and explain the differences.
5. Arrays: Many Values Under One Name
   Declare, index and loop over arrays without reading past the end. · Lab: Store four LED pins in an array and rewrite the running light with it.
6. Text as char Arrays versus the String Class
   Store and compare text both ways and know the trade-offs. · Lab: Store a name in both forms, print its length and compare it with typed input.
7. Receiving Single Characters from the Keyboard
   Use Serial.available and Serial.read to react to typed keys. · Lab: Switch an LED on with the key 1 and off with 0.
8. Reading Whole Numbers and Lines of Text
   Read multi-character input with parseInt and readStringUntil and handle line endings. · Lab: Type a number to set how many times an LED blinks.
9. Live Graphs with the Serial Plotter
   Format output so the plotter draws one or more labelled traces. · Lab: Plot a rising and falling counter and a button state together.
10. Building a Serial Command Menu
    Design a small text command set with help output and rejection of bad input. · Lab: Implement commands to switch four LEDs and print their status.
