Results for “Serial.read”
Small, practical examples. Search by task or narrow things down below.
Store and inspect a fixed set of bits
C++: bitset offers named operations and a readable binary representation.
C++✓ Tested
Store and retrieve a multibyte integer
Arduino / C: put and get copy the bytes of a typed value.
Arduino / C✓ Tested
Store samples in a fixed-size ring buffer
Arduino / C: The write position wraps while the storage size stays constant.
Arduino / C✓ Tested
Test any and all elements with predicates
C++: These algorithms stop as soon as their result is known.
C++✓ Tested
Toggle a bit with an XOR mask
Arduino / C: XOR flips selected bits and leaves all other bits unchanged.
Arduino / C✓ Tested
Toggle an output using an explicit software state
Arduino / C: Keep the intended output state in a Boolean variable.
Arduino / C✓ Tested
Track which union member is currently valid
C: An explicit tag tells callers which overlaid union value to read.
C✓ Tested
Transfer unique ownership with move
C++: Moving a unique_ptr leaves the source empty and gives ownership to the destination.
C++✓ Tested
Transform a vector into a separate result
C++: Pre-size the output before writing through its iterator.
C++✓ Tested
Trim surrounding ASCII whitespace
C++: Find the first and last non-whitespace bytes before taking a substring.
C++✓ Tested
Trim surrounding whitespace from an Arduino String
Arduino / C: String.trim modifies the object in place.
Arduino / C✓ Tested
Turn on the built-in LED
Configure the Uno’s LED pin as an output and drive it high.
LED_BUILTIN✓ Tested
