Find an array element
Use a bounded linear search over a C array.
C✓ Tested
Format several integers in a fixed buffer
Arduino / C: snprintf limits writes to the buffer size and includes a terminating null byte.
Arduino / C✓ Tested
Generate a stepped sequence
Linux Commands: Use seq when a command pipeline needs a numeric sequence.
Linux Commands✓ Tested
Generate and measure a short output pulse
Arduino / C: delayMicroseconds can create a short blocking pulse on an output pin.
Arduino / C✓ Tested
Give an LED pin a constant name
Arduino / C: Use const to name the built-in LED pin and reuse it in output instructions.
Arduino / C✓ Tested
Group related readings in a struct
Arduino / C: A struct keeps a sample’s fields together without dynamic allocation.
Arduino / C✓ Tested
Hello World: Blink
Arduino / C: Blink the built-in LED slowly and then quickly, repeating both rates in loop().
Arduino / C✓ Tested
Ignore small movements around a center value
Arduino / C: Values inside the deadband become zero while others keep their direction.
Arduino / C✓ Tested
Inspect a byte as hexadecimal
Arduino / C: Inspect a byte as hexadecimal on an Uno with the Serial Monitor set to 9600 baud.
Arduino / C✓ Tested
Interpolate between two calibration points
Arduino / C: Compute a fractional position before scaling to the output interval.
Arduino / C✓ Tested
Keep a counter from wrapping at its maximum
Arduino / C: Increment only when the value is below its limit.
Arduino / C✓ Tested
Keep a value inside an allowed range
Arduino / C: Keep a value inside an allowed range on an Uno with the Serial Monitor set to 9600 baud.
