Copy a string with a guaranteed terminator
Arduino / C: Reserve one character for the terminator when copying a bounded string.
Arduino / C✓ Tested
Count a button’s falling edge in the main loop
Arduino / C: Compare each reading with the previous state to detect transitions.
Arduino / C✓ Tested
Count a rising edge with an interrupt
Arduino / C: RISING triggers when the input changes from low to high.
Arduino / C✓ Tested
Count down with a bounded loop
Arduino / C: Count down with a bounded loop on an Uno with the Serial Monitor set to 9600 baud.
Arduino / C✓ Tested
Count five LED flashes with a for loop
Arduino / C: Repeat an LED action a known number of times and print the current count.
Arduino / C✓ Tested
Detect truncated formatted output
Arduino / C: snprintf returns the length it would have written, excluding the null terminator.
Arduino / C✓ Tested
Disable a service’s network interfaces
Docker / Compose: network_mode none leaves only the loopback interface.
Docker / Compose✓ Tested
Dispatch a command through function pointers
Arduino / C: A small function table can map validated command indices to actions.
Arduino / C✓ Tested
Dispatch a one-character serial command
Arduino / C: A switch provides explicit handling for accepted and unknown commands.
Arduino / C✓ Tested
Distinguish an empty input line from end of input
Bash Scripts: A successful read can return an empty value; its status indicates whether a line was read.
Bash Scripts✓ Tested
Drive the built-in LED low after turning it on
Arduino / C: digitalWrite changes the actual output level of a configured pin.
Arduino / C✓ Tested
Encode a value as little-endian bytes
Arduino / C: Store the least significant byte first when the protocol requires it.
