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

Arduino / C: Store several readings in an array on an Uno with the Serial Monitor set to 9600 baud.
Arduino / 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
