Accumulate characters in string and read characters from string. It is possible to store "namber" or "byte" in a string as a stream of characters. And from this string, read the characters indicated by the index. Characters will be displayed in the form of "number" or "byte".
XOD library to control the internal real time clock (RTC) of the Arduino Zero, MKR1000 and related boards. Tested using the MKR Vidor 4000. Wraps https://github.com/arduino-libraries/RTCZero
Generates rectangular waveforms of a user-defined duty and period. Waveforms can have a maximum frequency of 1MHz (period of 1 microsecond). Uses Paul Stoffregen's TimeOne library: https://github.com/PaulStoffregen/TimerOne.
Copy of std Ultrasonic range, but returns Max distance on failure so we can assume nothing close to us. My sensor seems to go low on ping capture, not success, so I changed timeout to max round trip to get full range.
